answer:
a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
what can increase its power?
answer:
Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage
