can you make an electromagnet with ac current
Electromagnet The energy loss per cycle of the AC current is constant for each of these processes, so the power loss increases linearly with frequency.
Electrical conductor In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions. Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.
