What create the magnetic force in an electromagnet?

Answer 1

The magnetic force in an electromagnet is created by the flow of electric current through a coil of wire. When a current flows through the wire, it generates a magnetic field around the wire. By coiling the wire into a coil shape, the magnetic fields from each turn of wire add up, creating a stronger magnetic field. This magnetic field can be turned on and off by controlling the flow of electric current through the wire.
