Top best answers to the question «Can electricity make magnets»

Thanks to Oersted and a few others, by using electricity, we can now make huge magnets… By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field.

By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field… There is another way that uses electricity to make a temporary magnet, called an electromagnet.

Can you make electricity from magnets? Yep, just as we can make magnets from electricity, we can also use magnets to make electricity. Here's how it works: A magnetic field pulls and pushes electrons in certain objects closer to them, making them move.

We recently published an article on the Power Electronics with the headline, “ Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this sounded like a perpetual motion machine and that it defies the law of conservation of energy and the law of thermodynamics.

It can, however, be converted from one kind to another—by solar panels that turn sunlight to electricity, or in the transformation of natural gas molecules to the heat that cooks our dinner and heats our homes. “Magnetism is a force, but it has no energy of its own,” says David Cohen-Tanugi SM '12.
