You’re literally one of the best communicators, and have a real gift at explaining concepts, complicated or not, in such an easy to understand manner. You explain it so well, that is almost impossible to not understand it afterwards. I can’t thank you enough for all your indirect help from your videos. Especially allowing us to view them for free is the real kicker. You have a great mind and a big heart to put the time and effort into your playlists. I’m going to school for my BS in mechanical engineering, and you literally helped me get straight As through all the pre req engineering courses, Calc based chem1&2, Calc based Physics1&2, and Calc 1&2. Please keep up the great work!!!! You rock!
honestly I should be paying this man several thousand a semester over my professors bc he teaches me way more and doesn’t judge me when I don’t understand how to do this lol
Your videos are SO amazing! I used them for Orgo 1 & 2 & for Physics 1 & now for Physics 2! I don't know how I would learn everything without them! Thank you so much!
For people like me, who can't understand something without understanding the basics first, the explanation with the X, Y and Z direction helped so much!
What an absolute MADLAD. This is almost everything we covered for this upcoming test. Couldn't pay attention in class but i'm getting a good grade now thanks to you! Love your video, will keep coming back.

This video discusses magnetism, magnetic fields, Ampere's Law, torque, solenoids, and physics problems. It explains the relationship between current and magnetic fields, the right hand rule, and how to calculate magnetic forces and torques in various scenarios. The video also covers the concept of magnetic dipole moments and the calculation of magnetic fields in solenoids. Key moments: 00:01 Magnetism involves attraction and repulsion between poles. Magnetic fields are created by moving electric charges, illustrated by the right-hand rule. -Illustration of magnetic field using the right-hand rule. The direction of the magnetic field around a wire can be determined by the direction of current flow and the curl of fingers around the wire. -Calculation of magnetic field strength. The equation B = u0 * i / 2πr is used to calculate the strength of the magnetic field created by a wire, where u0 is the permeability of free space. -Relationship between current and magnetic field strength. Increasing current increases the magnetic field strength due to direct proportionality. Decreasing distance weakens the magnetic field due to inverse proportionality. 08:03 Calculating the distance from a wire for a magnetic field strength involves using the equation involving current, magnetic field strength, and constants. Understanding the relationship between current, magnetic field, and magnetic force is crucial in physics. -Converting distance units from centimeters to meters is essential in physics calculations. One meter is equivalent to 100 centimeters. -The calculation of magnetic force involves the current, length of the wire, and the angle between the current and magnetic field. Increasing current or magnetic field strength results in a higher magnetic force. -The right-hand rule is used to determine the direction of the magnetic force acting on a current-carrying wire in a magnetic field. The force is perpendicular to both the current and the magnetic field. 16:07 Understanding the right-hand rule helps determine the direction of the magnetic force on a current-carrying wire. The magnitude of the magnetic force can be calculated using the formula F = ILB. -Using the right-hand rule to determine the direction of the magnetic force based on the orientation of the current and magnetic field. -Calculating the magnitude of the magnetic force on a wire using the formula F = ILB. 24:10 Understanding the right-hand rule is crucial for determining the direction of magnetic force. Magnetic force on a moving charge can be calculated using the equation F = Bqv sin(theta). -Right-hand rule helps determine the direction of magnetic force. Thumb points in the direction of current, fingers show magnetic field direction. -Equation F = Bqv sin(theta) calculates magnetic force on a moving charge. Current, charge, velocity, and angle are key factors in the equation. -Magnetic force direction depends on the orientation of charge and magnetic field. Use the right-hand rule to determine the force's direction. -For negatively charged particles, magnetic force direction is opposite to that of positively charged particles. Reverse the direction for negative charges. 32:15 A proton moving in a magnetic field perpendicular to its velocity will follow a circular path due to perpendicular forces. The radius of this path can be calculated using the equation r = mv / Bq. -Perpendicular forces cause a moving proton to follow a circular path in a magnetic field. The magnetic force acts as a centripetal force. -Electrons moving in a magnetic field experience a force opposite to protons, leading to circular motion in the opposite direction. The radius of the circular path can be calculated using the equation r = mv / Bq. 40:18 Calculating the radius of a proton's path involves using the speed, magnetic field strength, and charge. The energy of a proton in electron volts can be found by converting its kinetic energy. Wires with currents in the same direction attract each other due to magnetic forces. -Calculating the radius involves speed, magnetic field strength, and charge of a proton. The radius is found to be 2.09 centimeters. -Converting the proton's kinetic energy to electron volts gives 130,703 eV. The process involves understanding the relationship between joules and electron volts. -Electric potential is explained as energy per unit charge, with 1 volt equaling 1 joule per coulomb. The charge of an electron and its energy in electron volts are discussed. -Wires with currents in the same direction attract due to magnetic forces. The right hand rules are used to determine the direction of magnetic fields and forces between wires. 48:22 Understanding the force between parallel wires with current in the same direction, calculating the force magnitude, and applying Ampere's law for magnetic fields are essential concepts in electromagnetism. -Calculation of the force between two parallel wires with current in the same direction involves using the formula F = μ0 * I1 * I2 * L / 2π * R. -Ampere's law describes the relationship between current and magnetic fields, stating that the sum of magnetic fields around a closed path is equal to μ0 times the current enclosed by the path. -Solenoids, consisting of multiple wire loops, create strong magnetic fields at the center due to the cumulative effect of current loops, making them useful for generating powerful magnetic fields. 56:46 The strength of the magnetic field in a solenoid is directly proportional to the current passing through it and the number of turns per unit length, while inversely proportional to its length. -Increasing current or the number of turns per unit length in a solenoid enhances the strength of the magnetic field. -Decreasing the length of a solenoid also increases the strength of the magnetic field. 1:04:33 A current-carrying loop experiences torque in a magnetic field due to the force exerted on its sides. The torque formula is T = nIABsin(theta), where n is the number of loops, I is the current, A is the area, B is the magnetic field strength, and theta is the angle between the field and the normal line. -The torque on a current-carrying loop is due to the force exerted on its sides by the magnetic field. The force is perpendicular to both the current and the magnetic field, resulting in a torque that causes the loop to turn. -The torque formula for a single loop is T = nIABsin(theta), where n is the number of loops, I is the current, A is the area of the loop, B is the magnetic field strength, and theta is the angle between the field and the normal line. 1:12:56 Torque on a coil is greatest at 90 degrees between the magnetic field and the normal line of the coil, resulting in rotation. At 0 degrees, there is no torque due to parallel forces. -Explanation of torque at different angles. -Illustration of equilibrium at 0 degrees. 1:20:43 To find the maximum torque in a magnetic field, multiply the number of loops, current, area, and sine of 90 degrees. The magnetic field can be calculated by dividing the product of these values by the torque. -Calculation of maximum torque involves multiplying the number of loops, current, area, and sine of 90 degrees. -Solving for the magnetic field requires dividing the product of loops, current, area by the torque value
I’m studying for the MCAT and couldn’t remember these concepts at all. You helped me relearn material I haven’t seen in over 6 years. THANK YOUUU so so much!!
Thank you for being better than my professors! Been watching these as well as your calc 2 videos to either brush up (or full on learn) the content that I need to know for my exams and tests. You've been a lifesaver and make them much easier to understand! Don't stop making the videos you're helping so many people! Just wanted to say thanks!!!!!
you are an awsome teacher.i hope God blesses you abundantly. you are the reason why many students actually pass and understand STEM modules.. keep up the good work and know that we appreciate your work!
I was reading a book written by an electrician .not easy to understand plus the mistakes that were in it .after listening to yours carefully I understood it well.well explained and clear specially about the n The angle between normal line and direction of magnetic field.thank you so much.love your video.
I really like how you take time and build up the difficulty of the problems. Really boosts up my confidence as well as my understanding unlike college lecture which assumes you understand everything and just throws out abstract equations without explaining them.
I just took my time to watch and pause the video to calculate on my own, gauze what I scored in my CAT,, woow, thanks so much, I've just come back to thank you, I was really helped.
I currently am a junior taking ap physics 1, and I plan on taking ap physics 2 next year. Your videos thoroughly explain this topic in a simplistic yet advanced way that anyone can understand. I plan to watch all your ap physics 2 videos before I take ap physics 2 so I can have a further understanding
You are a great teacher. I attended the Physics classes but I don't understand the lectures at all. Your video is precious for me and it helps a lot to prepare my final exam. Thank you.

I hope you have a good day as well! Just finished studying for my exam thats about 7 hrs from now. You're the best teacher, my tuition should be going to you
that's pretty depressing that my tuition fee doesn't coincide with level of education in my college whilst the guy from youtube helps me get A in both calc and physics. you're litteraly the life saver, wish you all the best
Great video my friend I really like that you use such simple examples. It makes learning the equations and understanding the relationships between the variables quick and easy.
Thank you very much. I'm Italian and I've found this video really helpful and useful because I've learned something about the magnetic field and part of the mathematical English language at the same time. Subscribed. 😃✅
His notation of current out of page or into the page is incorrect. Current flowing out of the page, meaning towards you the viewer, should be a dot. Current flowing into the page, meaning away from you the viewer, should be an X. I was just confused, figured it might help someone out.
5:40 there is a small error on the blackboard. When R decreases, the magnetic field should decrease. You said that the radius is inversely proportional to magnetic field, but the blackboard shows the opposite. It's quite non-significant error. You're the best teacher ever.
@@kmn9568 The term “Boomer” is used to dismiss the older generation, meaning it is disrespectful. In this case it seems vain because physics formulas and books are written by our predecessors or “boomers”. Just trying to enlighten you since you asked. Enjoy.
@@will808080 we started to use the term boomer because we found it annoying when boomers flexed their boomerness to us about how "back in their day" kinda crap. I don't really need to be enlightened and I will use the term freely. In this case it is a joke I used to make a rhyme and I really don't see a reason why that's not a thing people would be ok with. It's the internet bud , if you weren't only subbed to every science channel you'd literally be spending your life correcting others rhetoric. Friendly advice, no one actually "enjoys" it and you will eventually get murdered with words. Enjoy
I learn more from you than my actual teacher, you literally cover everything I learn in lesson, and I know once I get arch your video I’ll finish knowing that I now understand
I am a huge fan of your videos! Everything from Organic Chemistry to Physics has been so helpful! A friendly suggestion would be to add timestamps in your description to help your viewers follow along or skip to the part they are most confused about :)
Up until this point I’ve only been using Flemmings Left Hand Motor Rule to determine the direction of force, magnetic field and current. The technique you showed here with the palm of your right hand is so much easier to use and remember. Thank you!
thank you very much, sir, now it's been 6 years since this vid was made and yet there is no brief,excellent and understandable video of electromagnetism. you are so talented in a way you can make everyone to understand physics and the vids on chemistry and maths are also awesome . what a blessed mind , thank you.
Love your videos, you ease alot of the anxiety that comes with learning these things with your well thought out explanations and train of thought that all flow very easily. Much thanks and appreciation from me!! :)
You are the best communicator and teacher I ever got, your way of explanation made me understand even what I failed to understand from my professor in 4 months. Thank you for being there for all of us. You deserve more, God bless you.. ✍️🙏🏼🙏🏼
I'm pretty sure I am late in trying to answer this but: For the left side, you place your thumb facing up, and your fingers facing to the right. Doing this will make it so that your palm faces away from out (into the page) For the right side, you place your thumb facing down, and your fingers facing to the right. Doing this will make it so that your palm faces towards you (out of the page)
you're my hero. cramming for an exam i haven't had a chance to study for because of work. is there somewhere we can donate to you? you got me through physics 1, you cover things in an hour that my prof takes 4 hours to do and you're so much more understandable. love your videos so much, thank you for all you do!!
good question, think about it this way; if you decrease the radius (or simply instead of going further away, get closer to the center) then the field is stronger there, this means that the strength of the field increases the closer you are to the center, decreases the further away you are, better?
I thought I understood this pretty well, until I confused myself by looking through the bewildering array of right and left hand rules here on the internet. Your video regrounded my understanding, thank you. Those other rules, with variable assignment of fingers and hands depending on the circumstance, were just too confusing.
at 5:37, you say that magnetic field decreases when radius decreases but isnt it the vice versa? i.e. the magnetic field increases when radius decreases?? also at 22:38 you say its out of the page but i think you drew the left hand instead of the right so it is into the page
u saved my life in orgo 1 and 2 , physics 1 and now 2. My professor doesn't explain anything if it wasn't for you I'd wouldn't have passed. Can you make Diff Eq and linear algebra video too please would help a lot Thanks
Hey man, I am following you from Saudi Arabia. How talented you are. I now understand more quickly. Greetings to you. You deserve a reward for your explanation.

56:46 The strength of the magnetic field in a solenoid is directly proportional to the current passing through it and the number of turns per unit length, while inversely proportional to its length.
-Increasing current or the number of turns per unit length in a solenoid enhances the strength of the magnetic field.
-Decreasing the length of a solenoid also increases the strength of the magnetic field.
1:04:33 A current-carrying loop experiences torque in a magnetic field due to the force exerted on its sides. The torque formula is T = nIABsin(theta), where n is the number of loops, I is the current, A is the area, B is the magnetic field strength, and theta is the angle between the field and the normal line.
-The torque on a current-carrying loop is due to the force exerted on its sides by the magnetic field. The force is perpendicular to both the current and the magnetic field, resulting in a torque that causes the loop to turn.
-The torque formula for a single loop is T = nIABsin(theta), where n is the number of loops, I is the current, A is the area of the loop, B is the magnetic field strength, and theta is the angle between the field and the normal line.
1:12:56 Torque on a coil is greatest at 90 degrees between the magnetic field and the normal line of the coil, resulting in rotation. At 0 degrees, there is no torque due to parallel forces.
-Explanation of torque at different angles.
-Illustration of equilibrium at 0 degrees.
1:20:43 To find the maximum torque in a magnetic field, multiply the number of loops, current, area, and sine of 90 degrees. The magnetic field can be calculated by dividing the product of these values by the torque.
-Calculation of maximum torque involves multiplying the number of loops, current, area, and sine of 90 degrees.
-Solving for the magnetic field requires dividing the product of loops, current, area by the torque value
Just passed physics thanks to this guy 🤘🏽
If my college didn't have an attendance policy, I would just skip class and watch this guy's videos
@@derpherpula592 Go the back of class, put on headphones, and watch his videos!
True
same here! :D
Same here sis🙌🏼🤟🏼
This one video sums up 2 weeks and 7 lectures for my physics class. 7 years later, THANK YOU!
Low voice is the only problem, I even used subtitles for better clarity. ABOVE ALL, I THANK YOU MISTER.
Thanks
This guy is worth his weight in gold honestly. You are just an amazing educator!! Thank you so much!!!!!!
I’m studying for the MCAT and couldn’t remember these concepts at all. You helped me relearn material I haven’t seen in over 6 years. THANK YOUUU so so much!!
I'm sorry, but it's illegal to be this smart in both chemistry and physics
And math also
maths too
And a little of biology.
He has a video on photosynthesis
Bruh come to Asia,bro if u r not smart in both u will become illegal 😂
And Biochemistry
Dude, I was able to finish my homework in less than 3 hours because of this video. You Rock!
got my physics exam in about 3 hrs, cramming in as much as possible.
How did it go?
How did it go
same.
How did it go?
I'm still curious to know your results.
I think you just saved my grade for an exam im cramming for. Thanks man!
Only reason why I'm passing Physics 2
this is physics 3 where i go to school
Ain’t that truth lol
Facts lmao
Physics galaxy is best chanel for physics lover
Clorox Bleach me too, but I know some people that take electromagnetism/modern physics second year then take optics/pressure/laws of thermodynamics
Thank you for being better than my professors! Been watching these as well as your calc 2 videos to either brush up (or full on learn) the content that I need to know for my exams and tests. You've been a lifesaver and make them much easier to understand! Don't stop making the videos you're helping so many people! Just wanted to say thanks!!!!!
you are an awsome teacher.i hope God blesses you abundantly. you are the reason why many students actually pass and understand STEM modules.. keep up the good work and know that we appreciate your work!
I was reading a book written by an electrician .not easy to understand plus the mistakes that were in it .after listening to yours carefully I understood it well.well explained and clear specially about the n
The angle between normal line and direction of magnetic field.thank you so much.love your video.
I really like how you take time and build up the difficulty of the problems. Really boosts up my confidence as well as my understanding unlike college lecture which assumes you understand everything and just throws out abstract equations without explaining them.
so true!!!
I just took my time to watch and pause the video to calculate on my own, gauze what I scored in my CAT,, woow, thanks so much, I've just come back to thank you, I was really helped.
this is almost 2020
AND THIS VIDEO IS HUGELY HELPFUL
very glad you made this
You save me a lot of time
I currently am a junior taking ap physics 1, and I plan on taking ap physics 2 next year. Your videos thoroughly explain this topic in a simplistic yet advanced way that anyone can understand. I plan to watch all your ap physics 2 videos before I take ap physics 2 so I can have a further understanding
shouldn't magnetic field (B) increase as distance from the wire (R) decreases?
yea i noticed that too
He meant increases, but he drew it as decreases
I noticed it too.
Yea he meant that
no because the strength looses as distance increase as density of field lines get decreased at a increasing distance
You are a great teacher. I attended the Physics classes but I don't understand the lectures at all. Your video is precious for me and it helps a lot to prepare my final exam. Thank you.
Man, magnetism is easy af with your lessons! I couldn't understand a word when I read that on my book. Thanks )
This is so helpful. I am only 16 min in and already have 3 pages of notes! Great details here! Bravo, Bravo!
man you the best, at what you are doing am so grateful.
themba xulu Hi ,There are no coincidence in this life and I know for sure that GOD is giving all of us the chance to know him better and to make a relationship with him , and also have a great life : the answer is the prophet Muhammed Peace be upon him , he is the latest messenger from GOD to all mankind ,
Muslims were once the leaders of the world when they were practicing the commandement of the Curan ,
I know that you will delete this message but please take a few minutes of your time and make some research about it .
I am sending this message to everyone I can reach , everyone deserve to know the truth ,
Peace be with you and good luck.

What the fuck does this have to do with magnetism?
Lol
themba xulu I
Kobee R nice
I hope you have a good day as well! Just finished studying for my exam thats about 7 hrs from now. You're the best teacher, my tuition should be going to you
Thank you so much for your explanation of magnetism. You explain the subject matter way better than my textbook.
that's pretty depressing that my tuition fee doesn't coincide with level of education in my college whilst the guy from youtube helps me get A in both calc and physics. you're litteraly the life saver, wish you all the best
Great video my friend I really like that you use such simple examples. It makes learning the equations and understanding the relationships between the variables quick and easy.
Can I just say, god bless u! You save me in every course and no one explained to me the RHR so clearly as you did. Thank you!
Physics is rough but these legacy videos are coming in clutch. Thank you for the clarity and brevity.
at the example:
4Pi*10^-7*I / 2Pi*r I simplyfied with 2*10^-7*I / r and got the same result. Very nice video bro
you have a very calm voice that would attract even the deaf
Say what?
we found the deaf person lol
BLESS YOU SO MUCH. SECOND TIME WATCHING THIS VID IN MY LIFE AND ITS BLESSED ME EACH TIME
at 5:55 the B suppose to increase when R decrease right...because its is inversely propotional.....??
Yea...that's what I thought??
He said the right thing but made the direction of the arrow wrong and yes you are right
Yeah, I was a bit confused
Yeah, I was a bit confused
the way the physic flow in you...simple and easy to understand you're gifted Man.
Dude. I've been to physics classes watched videos from M.I.T. professors and this video trumps all those guys. Keep it up. Thank you.
Talented tutor ever ,
You deserve an Oscar
Thank you very much. I'm Italian and I've found this video really helpful and useful because I've learned something about the magnetic field and part of the mathematical English language at the same time. Subscribed. 😃✅
No problem
Which software to you use to make your videos? :-)
you are the man of Magnetism.....seriously outstanding
Thank you hopefully this will help me on physic portion of the MCAT. I definitely feel more confident.
I would have failed if it weren't for u and ur free service. Dude deserves a noble peace price
You have no idea how much you have helped me! So informative and amazing! :)
One of the best teachers😮
5:30 the arrow should point upwards for R, since it is reversible related to B.
Bruhhhhh, if you know how many times you have saved me during my final exams for my semester ‼️‼️‼️❤️❤️❤️❤️❤️... Keep doing this 💯
His notation of current out of page or into the page is incorrect.
Current flowing out of the page, meaning towards you the viewer, should be a dot.
Current flowing into the page, meaning away from you the viewer, should be an X.
I was just confused, figured it might help someone out.
I was wondering this too! I thought I had it backwards but glad to see someone else caught it.
5:40 there is a small error on the blackboard. When R decreases, the magnetic field should decrease. You said that the radius is inversely proportional to magnetic field, but the blackboard shows the opposite. It's quite non-significant error. You're the best teacher ever.
When online physics is taught by a boomer
Go to the Organic Chemistry Tutor
@@bjonu fs, just wrote this in good fun when my physics teacher sped up the pace x10000
We are all just trying to learn what are elders and ancestors discovered. Try not to be too vain guys.
@@will808080 isajoke? Wdym vain i just felt like writing sum funny
@@kmn9568 The term “Boomer” is used to dismiss the older generation, meaning it is disrespectful. In this case it seems vain because physics formulas and books are written by our predecessors or “boomers”. Just trying to enlighten you since you asked. Enjoy.
@@will808080 we started to use the term boomer because we found it annoying when boomers flexed their boomerness to us about how "back in their day" kinda crap. I don't really need to be enlightened and I will use the term freely. In this case it is a joke I used to make a rhyme and I really don't see a reason why that's not a thing people would be ok with. It's the internet bud , if you weren't only subbed to every science channel you'd literally be spending your life correcting others rhetoric. Friendly advice, no one actually "enjoys" it and you will eventually get murdered with words. Enjoy
I learn more from you than my actual teacher, you literally cover everything I learn in lesson, and I know once I get arch your video I’ll finish knowing that I now understand
I am a huge fan of your videos! Everything from Organic Chemistry to Physics has been so helpful!
A friendly suggestion would be to add timestamps in your description to help your viewers follow along or skip to the part they are most confused about :)
I landed on this tutorial when I was sleepy but the sleep disappeared, I am really grateful thanks Tr.
just thank you, saved my life
Up until this point I’ve only been using Flemmings Left Hand Motor Rule to determine the direction of force, magnetic field and current. The technique you showed here with the palm of your right hand is so much easier to use and remember. Thank you!
You're really the best teacher of physics I've ever learnt from?
your presentation is fabulous....you. clear my. confusing ....
Excellent excellent excellent!!! Thank you, information is still blessing those 5 years later, and will continue to do so going forward! 🙏
Man wtf i spend two week in class now learning a single thing and it only took one video to teach me everything????
thank you very much, sir, now it's been 6 years since this vid was made and yet there is no brief,excellent and understandable video of electromagnetism. you are so talented in a way you can make everyone to understand physics and the vids on chemistry and maths are also awesome . what a blessed mind , thank you.
Love your videos, you ease alot of the anxiety that comes with learning these things with your well thought out explanations and train of thought that all flow very easily. Much thanks and appreciation from me!! :)
Thank you so much! I am writing physics in two days, and I already feel confident thanks to you.
I just love this person ...can someone tell me his name ?? How he looks like ?? I want to see this genius
You are the best communicator and teacher I ever got, your way of explanation made me understand even what I failed to understand from my professor in 4 months. Thank you for being there for all of us. You deserve more, God bless you.. ✍️🙏🏼🙏🏼
1:04:58 when I use the right hand rule, the force goes out of the page? I'm confused about that.
I'm pretty sure I am late in trying to answer this but:
For the left side, you place your thumb facing up, and your fingers facing to the right. Doing this will make it so that your palm faces away from out (into the page)
For the right side, you place your thumb facing down, and your fingers facing to the right. Doing this will make it so that your palm faces towards you (out of the page)
you're my hero. cramming for an exam i haven't had a chance to study for because of work. is there somewhere we can donate to you? you got me through physics 1, you cover things in an hour that my prof takes 4 hours to do and you're so much more understandable. love your videos so much, thank you for all you do!!
the sentence that i love most , "we can get rid of it" :)
This has really helped me a lot thank you soo much and continue doing ur thing❣️
My savior was on minute 47:47. That interaction had been bugging me for the entire unit, I finally understand. Thank you!!!
5:55 if you increase the strength of the magnetic field doesn't the radius decrease because there is an inverse relationship B=1/R
good question, think about it this way; if you decrease the radius (or simply instead of going further away, get closer to the center) then the field is stronger there, this means that the strength of the field increases the closer you are to the center, decreases the further away you are, better?
Ohh Shit I get it now, good explanation thanks man, you should start your own channel
no problem man, if you need anything else let me know and i would start a channel but im terribly awkward and i dont know anything about editing xD
I struggle with scalars and vectors, especially when to use Sin and Cos and Tan
wow the way u explain everything in easy words and like i dont have previous knowledge is so helpful. You can tell u truly understand the concepts.
I thought I understood this pretty well, until I confused myself by looking through the bewildering array of right and left hand rules here on the internet. Your video regrounded my understanding, thank you. Those other rules, with variable assignment of fingers and hands depending on the circumstance, were just too confusing.
let me just say that you are the most talented and awesome teacher ever. I know this section like the back of my hand thanks to you!!!!!!!!
Physics test tmrrow morning. Let's see how it goes hehe.
u saved me.i have gone blank in my zoom and idk what happened.its just 2 days to my phy test now ik what i have to do
who’s watching this during quarantine
what's the logic of this comment?
@@kavyajain2210 lol
You are the best. Studying for Phys 2 final and you are an angel
at 5:37, you say that magnetic field decreases when radius decreases but isnt it the vice versa? i.e. the magnetic field increases when radius decreases??
also at 22:38 you say its out of the page but i think you drew the left hand instead of the right so it is into the page
1. yes youre right. its inv proportional
2. No this one is still out of the page
F=BIL is not left hand rule?
Thanks for this amazing class. I just learned a subject that I have always struggled with
Greetings from São Paulo!!
I should've skipped the last 2 weeks of class and just watched this video instead, sending links to everyone I know
u saved my life in orgo 1 and 2 , physics 1 and now 2. My professor doesn't explain anything if it wasn't for you I'd wouldn't have passed. Can you make Diff Eq and linear algebra video too please would help a lot Thanks
I came here without having a test to take urgently. I guess I'm improving.
Well, updates:
I left at once and I'm coming back now the test is tomorrow morning
