Question

explain why a solenoid has insulated wire?

Answer 1

Insulated copper wire is used in making solenoid, because if we use without insulation current flows in the shortest path (straight path) and gets short circuited, so that it cannot behave as an electromagnet. ... To provide electromagnet, our coil will not magnetise fully and we will not get strong magnet.
