Greetings. I need help making an electromagnet. I would make it out of copper coil and a rare earth metal, undecided on that point yet. I know how to make a basic one but this one has to have two (2) cylindrical poles, that would remain vertical above each other. It cannot be a horseshoe magnet, because I want an even and symmetrical magnetic field. Even two separate magnets of different polarities would work fine for me

Do you know anything about electromagnets? I don't know how to help you, as this is a pretty broad question.

I have made electromagnets before this. I just need help making this exact setup. How would i control the polarity of an electromagnet is a better way to ask that. I need them also to be on the same circut if possible. And shouldi use AC or DC power.

Making an electromagnet

Polarity is controlled by the direction of current. Switch the direction and the polarity switches. I don't know why you would use AC power, as that would be more for making a transformer, not an electromagnet. If you want them on the same circuit...just put them on the same circuit?

Thanks. I guess my question about the same circuit thing was how do I have the DC current going in two separate directions while still being on the same circuit.

Just wind the magnets in opposite directions.

Just be very careful beatlemaniac, clearly, you know very little about electromagnetism or electricity to be given advise over a forum like this one. Nobody around here is going to want to be liable for anything you do based on their advise. Go to a teacher, join a physics club or something, do not go at it alone at this time.

Be safe.

Thanks for the concern Gsal. I do know alot about electromagnets and electromagnetism. I have made them before and I have made ones of different polarity. I just needed help putting them on the same circut.
