I have some questions: • Can I make a permanent or semi-permanent magnet by using the method shown and a 9 volt battery instead? • Would it make the magnetic field stronger than at 1.5 volts? • Is it a problem if the screw heats up? Would it compromise the magnetic field or make the permanent magnet weaker by doing so?
3 questions: 1. does it have to be copper wire? 2. can this be scaled up and how easy would it be to do? 3. can you think of any projects where you might use an electromagnet?
Duh my brain wasn't quite on when. I typed that comment but the other questions still stand. I know it can be upscaled. Because we have electromagnets that can pick up cars.
@@RoborobsComputersconnect it to a power grid with the biggest copper wire you can find and a very large steel bar. Then I would duct tape it to an excavator and use it to lift small cars. (Do not take my word for it, I have not tested it, nor do I plan to.)
I agree with CrazyRabidz's comment. I was about to show grade school students how to make this. I wondered about the "short circuit" as well. I practiced this at home. It generated enough heat at my fingers that I threw the battery away. He did mention about using electrical tape but failed to mention what the tape is for. It is indeed a "short circuit" with a 1.5V battery.
You should mention the direction of coiling with respect to the direction of the current bcoz it could cause both repulsion and attraction and repulsive case can't be observed unless u use another magnet
Please explain. We were doing this is science today and couldn't figure out why it wasn't attracting the paper clips so my teacher said that I should do some research
Not quite what your thumbnail showed but thanks for bringing back some childhood memories lol. I used to do this sort of thing when I was ten or so and now when I think back on some of my other early experiments with more volatile materials I wonder how my poor parents put up with it :)
after a prolonged time it become a permanent magnet. It does work from mains electricity because it's a alternating current but works with a battery because it's a direct current. if I am wrong let me know my previous experiment failed due to this.
After watching this, tried it with a double A battery and some insulated thermostat wire, didn’t magnetize but it was hot! 😂 Electrical tape began melting even!
Anyone should be careful with such experiments.. heat is quickly building up in the nail and the wires... you should never leave such a loop connected too long. This is almost a short circuit, considering that the coil has a "significant" inductance...
Use some electrical resistance. It will reduce the current according to Ohm's Law : U = RI. For a given tension U, if you increase the total resistance of your circuit R (by adding some electrical resistances), the current I will be smaller. I believe this should reduce the risk of overheating the wires / the battery
Roman, the best way to strip insulation from enameled wire is to sand it off. It's real easy: get a piece of fine grit sandpaper (220 grit is just fine) that's...oh, 3cm x 6cm is plenty big...fold it in half with the sand on the inside, stick the end of the wire in the fold, pinch and pull.
I just use a match/lighter or flame of some sort and burn it off it works for all but the finest of of wire (but then again try sanding or scraping some of those hair fine wires its a nightmare)
I know I may be asking alot but, do you think it'd be possible if you could make a video on how to make a Electromagnetic field? (just a tiny one not some massive nonsense)
Here's one for ya...... Get a sphere of iron.(hollow) about 8 inches round.... Wrap with 1140 wire... Rig 4 car batteries into cycle...(well below household ac current. One wrapped plug in...and watch your electronics in a 100 foot circle get fried.
Do you think this will help me with my Sega Dreamcast? I got a screw bit stuck in one of the deep outer holes and I cant get to it to fall out because it has some magnetism in it.
Looks like the current is traveling perpendicular to the battery, the magnetic field is going straight up, and the electric force is directed towards the right. Uncle Tesla was right! LOL
So if I used a large metal rod a car battery and 4 gauge wire could I make a giant version of this?
Yup
I destroyed an RV by doing this lmfao I used 4 car batteries
Yes

copper is super conductive

thanks, my science teacher will be proud

HEAT = ENERGY

Same as yeetus please explain to us
my guy........ plx explain
@@yeetus_the_feetus-_-9324 Turn the battery around. If it doesn't work one way, flip the polarity. It is either one or the other.
I did the magnet for a science project and got 1st place
Nice
me ro
me to
Very good
Ls.nando Congratulations!
Perfectly explained.Thank you
That's why Thor calls his hammer by electromagetis😂😂😂😂
Not quite what your thumbnail showed but thanks for bringing back some childhood memories lol. I used to do this sort of thing when I was ten or so and now when I think back on some of my other early experiments with more volatile materials I wonder how my poor parents put up with it :)
I came here from Dr. STONE
Yes but does it work or dors japan lie to us ?
Lmaaaoooo I thought I'm the only cringe
Same here
meee too
lmao same
Great experiment. Thank you for the great presentation, simple and to the point.
Thank you so much it's easy to understand from your video 💯
Thank you for good magnet so helpful 😁😁😁
Απλά και κατανοητά. Μπράβο φιλαράκι
Cool
Op in the chat
Basice idea... good one mate
Wow!That's really tremendous. That's important fact for mine.Great presentation.Thank you so much indeed.
I was expecting an impossible ingredient when he opened the can lol and some plutonium lmao
Gute Darstellung. Sehr gut nach zu bauen.
You saved my science assignment marks .. Thank you😅😅😅❤❤
You said that everyone can make electric magnet in 30 second so why your video is 2 minute 🧐🧐
Duuuuhh, idk maybe cause he tells you what you'll need followed by what you do step by step how to do it yourself in 30 seconds. Derp-e-derp
bruh its true noor
after a prolonged time it become a permanent magnet. It does work from mains electricity because it's a alternating current but works with a battery because it's a direct current. if I am wrong let me know my previous experiment failed due to this.
Tips: You should use enameled copper wire.
Wonder if there is a way to reverse the polarity in a bigger version to make it levitate
After watching this, tried it with a double A battery and some insulated thermostat wire, didn’t magnetize but it was hot! 😂 Electrical tape began melting even!
Very handy tutorial, thx
best way of making electric magnet
Anyone should be careful with such experiments.. heat is quickly building up in the nail and the wires... you should never leave such a loop connected too long. This is almost a short circuit, considering that the coil has a "significant" inductance...
So, how can we make a permanent low current electromagnet ?
Use some electrical resistance. It will reduce the current according to Ohm's Law :
U = RI. For a given tension U, if you increase the total resistance of your circuit R (by adding some electrical resistances), the current I will be smaller. I believe this should reduce the risk of overheating the wires / the battery
I know it too late , the battery almost explode
Great intro! 😌
I need this video to make my stand ability thanks

It's superb I made it in 33seconds
OMG IT ACTUALLY WORKED!
I tried making mine, but it did not work
Ugh
U have to make more coils
Thanks so much
I like this very much
DR STONEEEEEEEEEEEEEEEEEEEEE
That was so good !!!
Nice
😮😮😮wow amazing
May I know if the magnet has north or south pole and if yes, which one is it?
I know I may be asking alot but, do you think it'd be possible if you could make a video on how to make a Electromagnetic field? (just a tiny one not some massive nonsense)
Simple and straight to the point, thanks.🇬🇧
Thank u it was a really good and cool magnet
Hi
You saved my school project
Thanks
Can I make one 3' long that I can hang behind my quad and pick up nails and other tire fetters
Bravo Ursule!
Very good idea 😎😎😎😎😀😀😀👍👍👍👍👍🔥🔥
Thanks for the given video
So interesting! 👌
I’m going to build my future out of magnets 😍😇
Awesome job sir tnx lot 😊
Thank you 😊
can someone tell me how it works? like how the battery makes magnetic thingy?
Here after loosing an important lawnmower part in the front yard
Did you find it?
Lol
For me it didnt do a magnet, the battery just went so hot
Does insulation interfere with field conduction of the coil?
Not talking about the tips, but the coiled part
Ducky Man Technically yes, but the insulation is needed to prevent short circuiting.
Thank you for this video
We did this in class
Here's one for ya......
Get a sphere of iron.(hollow) about 8 inches round....
Wrap with 1140 wire...
Rig 4 car batteries into cycle...(well below household ac current.
One wrapped plug in...and watch your electronics in a 100 foot circle get fried.
stupid question: what would happen if you made something slightly bigger and plugged the ends into an electrical socket?
You are the best bro 🙏
Wow that's cool! Fsr idk how the tape worked. It didn't work for my lil brother🤷♀
I like your intro
I was not understand this activity through book but through this video I have understand this activity
You are best
Hi. Do the coil need to be parallel to the battery or can you move the coil away from it?
It can be in whatever orientation you want it to be in as long as the wires don't touch
Now that is science
Nice job Roman. Now, show us how to make a solenoid. something that could be used for a secret compartment.
I'm not a fan of science but ngl that was pretty cool
Thank you for allowing me to hear your amazing voice. Also, thank you for recording and uploading this video.
Can you please help? I tried making this but mine never makes any magnetism. I have copper wire but im not sure if its insulated or not
There will not be any short circuit?
Good job
And thanx alot
Do you think this will help me with my Sega Dreamcast? I got a screw bit stuck in one of the deep outer holes and I cant get to it to fall out because it has some magnetism in it.
Must it be copper??
me at 3am in the morning: I'ma make a rail gun that shoots explosives out of this highly informational video
What's the difference between putting more copper wire and less copper wire?
Can u help me out plzz...anyone?
i believe the intensity of the magnetic field gets higher the more copper wire there is
Nice video
did you just use magnetic copper wire
Very nice
I did all the things you told , batteries are also new what should I do??
Hey can I use this magnet for magnetic Levitator stand?
niks Rathore Yes but permanent magnets will be better, so you don’t have to power it the whole time
Hey bro awesome idea
DR STONE
What happens if i dont use electrical tape and hold both ends with my bare fingers?
I did that and i do not recomend
Good, my son like the tutorial, keep it up.
Nice
amazing :D
Well, guess i failed the AQA Physics 3 GCSE 6 marker question about how to make this electromagnet lol
awesome brother
Your voice is very good
Can batteries explode?
Looks like the current is traveling perpendicular to the battery, the magnetic field is going straight up, and the electric force is directed towards the right. Uncle Tesla was right! LOL
Amazing tarekkk
What 😮 l don't now how to do that 😅
Build your electric magnet in 30 seconds, why is the video 2.19 long and not 30 seconds
very nice. I will show to my grandchild.
wht r u using in the last time to check out whether it is magnet or not
Aarati Agrawal what you have given the comment is not good
very nice you tell the name of things which you use is very nice
Since the coil is acting as a Heater element too, is it safe or it can cause blaze?
