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
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!
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)
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)
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
I believe this works because the electricity creates a magnetic field so although I haven't tried it, it should probably work with any material that's conductive
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.
