It has to be a magnetic material, iron is the best. Mild steel is ok but stainless steel not.

You can make any metal piece of any size an electromagnet by wounding a conducting wire around it and passing an electric current through it....
A Bitter electromagnet is a strong electromagnet constructed from circular conducting metal plates and insulting spheres stacked in a helical configuration, rather than from coils of wire.

Wrap wire around a metal core. Like all other electromagnets.
An electromagnet is a magnet caused by electricity.
you rub anything metal on a magnet (a paperclip) and its magnetises it (for awhile any ways) but if you add a electric circut you have a electromagnet to turn on or off. you rub anything metal on a magnet (a paperclip) and its magnetises it (for awhile any ways) but if you add a electric circut you have a electromagnet to turn on or off. this answer is by a 14 year old boy at chillhowiee middle school j.a
Ferrous metal.
Their are no objects made of metal, anything that claims to be made of metal is a talking object, and that's weird.
The switch is turned on to activate the electromagnet, and metal is attracted. Turning off the switch stops the electromagnet from working, and metal is no longer attracted.
An electromagnet is a type of magnet whose magnetic properties stem from electricity. The earth has a lot of electromagnet waves running through it's surface, which come from the polarization of the planet. A more simple electromagnet can be made by wrapping wire around a metal object and connecting the wire to a battery (just be careful).

It is a magnet which moves metal around the scrap yard. Scientific explanation = It s a big round magnet which is actually an electromagnet. This allows the magnet to be turned on then off. When turned on the electromagnet attracts any magnetic substances. This is why most cars are made of something magnetic! You can move this electromagnet around because it is a crane you pick stuff up move it and then drop it by turning the electromagnet off!
