Question

what is solenoid? How does a solenoid behave like a bar magnet ​

Answer 1

Solenoid is the generic term for a coil of wire used as an electromagnet. It also refers to any device that converts electrical energy to mechanical energy using a solenoid. ..

Solenoid behaves like a magnet as it has a soft iron core with insulated copper wire over it. When a current is passed through the solenoid, magnetic field is produced around it. The magnetic field produced is similar to the magnetic field of a bar magnet.
