Question

An electromagnet coil is made of an
insulated wire. Explain the reason for this​

Answer 1

Answer:

The copper wire used in an electromagnet is insulated with a coating of nonconductive insulation like plastic or enamel in order to prevent the current from passing between the wire turns. ... If uninsulated wire is used the electricity will run across the windings and not make loop after loop and create a magnetic field.
