Question

What is a solenoid? Compare the
magnetic field produced by a solenoid
with the magnetic field of a bar
magnet. Draw neat figures and name
various components​

Answer 1

Answer:

The magnetism retains in the bar magnet naturally but in solenoid the magnetism is there so long current flows through it. 3) Magnetic field of a bar magnet emanates from throughout the body of the magnet, with more intensity at the poles. While there is no field emanating from the lateral surface of the solenoid.
