Your videos will last forever, Eugene. You are helping people all over the world to understand physics better. Keep up the good work! I love your videos!!
@@EugeneKhutoryansky I dare you to make a video about parametric excitation of electrical oscillation where the inductance of an inductor part of the LC tank circuit with initial voltage, is oscillated with twice the resonant frequency, either mechanically or electrically with perpendicular field.
This video inspired me to do a project today: build a simple unpowered hysteresis tool for magnetizing/demagnetizing the tips of screwdrivers. I love animated physics, but I find it helpful to also build or do something related.
I remember like it was yesterday the physics professor at the engineering university I went trying to explain this subject with a way more theoretical approach and at the end of the lesson I only had these equations and demonstrations without really knowing what the hell this was all about. Years later I see this video and now everything is so damned clear. I really love your videos and I really wanted them during my university years.
That was an exceptionally well animated and well described educational piece on magnetic fields, magetization, demagnetization and inductance, as are all your other videos about all other physics subjects! I already had a fairly solid understanding of many fields of physics, but these videos give me a depth of understanding that transcends even the deepest literary explanations! I find myself rewatching them from time to time, not because I forget... but because I remember how well made they are, and want to enjoy them again!
I have become a teacher of electrotechnics at secondary industrial school this year. My goal is to spread the knowledge and wisdom as well as this channel that I followed through all 5 years in the university. Bless you, Eugene :)
Magnetic fields don't like to change and resist it. When they do change, it's slowly and it heats up. My grandfather is a magnetic field! If Jeopardy is on, he is stuck to the TV, but when the chatty neighbor comes over to watch with him, his neck starts steaming and he's gone! He even keeps little magnets in his pockets, "just in case" he might need one. No one knows what for. He hums that tune, the waltz, Blue Danube? when he's concentrating (in the restroom) on something
I teach for an electrical apprenticeship program and use these videos teaching electrical theory. I’ve never found another platform that makes these concepts more simple to understand. Thanks for the amazing animations
@@EugeneKhutoryansky what about a video explaining the mechanics behind Pauli exclusion principle? A lot of people try to say that there isn't any repulsion going on, instead that it's merely Pauli exclusion, and I think that breaks logic because the particles don't care nor know that they're 'forbidden' to be near or in the same state, some type of mechanism must prevent one particle from dropping to a lower state that's already occupied by another particle, and that seems like a repulsive effect, especially in obvious cases like where they repel the force of a collapsing star.
Marino, I have a detailed explanation of the mechanics behind the Pauli Exclusion principle and the apparent repulsion in my video at ruclips.net/video/Zlp2GQ3OLeE/видео.html
I am a student of electrical engineering and I have seen these graphs before, but I have never really understood what they meant. Thank you for another moment of enlightenment.
would have liked more intuitive descriptors of what is going on, like the energy lost due to heat, the difference between energy from and to the circuit...got lost there...
I really respect and admire your videos like none other! The level of conceptual clarity and understanding attained by seeing your videos is just exceptional and class apart! Thank you so much for helping us such profoundly with your talent!
Great video. Could you do a similar video but with superconductors and the magnetic fields they produce in relation to current and voltage. Unless you have already done this subject. Another idea is to do a video on the geometry of magnetic fields by altering the shape of the flux material in donuts, squares, lines and the interaction of two magnetic fields geometry.
And the funny stuff is that exist materials created in lab that exhibit the reverse of an hysteresis loop. The material doesn't lost energy but gain it! It happen in some specific condition such as low temperature and so on. The effect is called "inverted hysteresis" or "proteresis", the loop look like the same as a regular one but travel in reverse!
Thanks for explaining one of the most counterintuitive, complex core concept of universal invisible physical forces hidden fields entangled fluxes governing flows within, between and across quantum technology singularity realms at helm of wonderful awe inspiring depth, width, height and length in 4 dimensional Spacetime Ordered Spheres Influencing both microcosm and macrocosm levels.
In the electrical power industry, instrument transformers to measure current can have large heavy steel cores. The amount of magnetic field in the steel when there is no current flowing is called the remenance factor, and the core gets demagnetized after testing. I know because I test large current transformers that can be 3 meters tall and weigh hundreds of kg.
Nice explantaion. Its not usual to see the exchanged energy as the orange highlighted areas. On minute 7:00 it could also be assumed that frequency is low so eddys are negligible
Just an idea, albeit probably a challenging one. I wonder if you'd be able to intuitively explain concepts like spinors, Klein-Gordon equation or Dirac equation, and their role in electromagnetism.
Nice video, I had to replay many sections to align my theoretical knowledge to the practical demonstration. Iron losses and copper losses could also have been added. Thanks 4 the video.
Great video Eugene ! You could continue this topic and show how a high reverse voltage is created when the current is abruptly stopped and makes a flyback effect. 😁
Thanks for providing such an awesome visual resource! Taking the second half of upper-division electrodynamics at university right now and it's my least favorite part of physics to study (except possibly Thermo) but these videos help make it more bearable.
Thanks for this explanation!! I guess an air core inductor will increase it's B-field (low) with increasing current...until the coil just burns up...@@EugeneKhutoryansky
I deal with hysteresis every day in the valves that i assemble and calibrate and test . My question is ... how would i reduce hysteresis ? I have a coil and a frame magnet thats magnetized . I have a downward plot and a upward plot . And we have a customer driven spec. To be under 1.8 milliamps.
Please make some more videos explaining about heat transferring, the kinetic-molecular theory and 1st law of thermodynamic, I think there are not enough videos of that topics here. Your other videos about electromagnetics and maths are very intuitive, thank you for that
I already have several videos on that. For example, my video on Molecular Temperature & Degrees of Freedom is at ruclips.net/video/nqGtji3ZjoI/видео.html

Egg laying hens are the worst treated of all farm animals, far more so than the animals raised for meat. For example, male chicks are thrown into a grinder, even at the "cage-free" egg farms which claim to care about animals (due to the fact that the male chicks will never lay eggs).
I love your content. Your explanations are always marvellous and your animations are constantly getting even more superb. Thank you for being so passionate. Keep it up Eugene.
Can you give more insight into inductors about why the inductor first opposes the current passing throught it and oce the current reaches a specific stable value why it opposes the current from reducing.... I think it has to do with the information that the extreme ends of the inductors first get the information of the circuit switch being turned on and off and the coils at the centre of the inductor can't get that information at that time i.e., it takes more time to get that information because information travels at exactly the speed of light... Anyway many people say that there is a great similarly between electric circuits and hydraulics ( analogy of current flowing through resistances with fluid flowing through pipes ) can you please make a video on this to get a better insight of voltage analogous to pressure and current analogous to volume flow rate of the fluid?
Inductors simply try to prevent the current flowing through them from changing. I have a video explaining inductors at ruclips.net/video/ukBFPrXiKWA/видео.html
I have a number of videos on thermodynamics. My main Thermodynamics video, titled "Thermodynamics and the End of the Universe" is at ruclips.net/video/GOrWy_yNBvY/видео.html

Please Help Me A moving rod placed in a stationary U-shaped frame. When a conductor (the moving rod in this case) moves perpendicular to a magnetic field, an electromotive force (EMF) is induced according to Faraday's law of electromagnetic induction. The rate of change of magnetic flux through the loop formed by the moving rod and the stationary U-shaped rods is given by = B⋅L⋅V where B is the magnetic field strength,L is the length of the rod, and v is its velocity. Now, the negative of rate of change of magnetic flux = work done by electromagnetic force throughout the loop, which is BLV+IR, i=current , r=resistance But this leads to that,BLV=BLV+I--->>IR=0 , means electric current through loop is 0, So, Just Please Clarify My Confusion
Can you help me Why, when you have higher voltage you have lower current? Voltage is potential power? And current is the electron flow tru a circuit, right? I never could catch the flow of this one on school.
For a resistor or light bulb, a higher voltage gives a higher the current. However, what is going on here with the coil is that the voltage is proportional to the rate at which the magnetic field is changing.
