Question

what is a solenoid?compare the magnetic field produced by a solenoid with the magnetic field of a bar magnet .​

Answer 1

Explanation:

cylindrical coil of wire acting as a magnet when carrying electric current.

The nature of magnetic field lines produced by a solenoid is similar to that of a bar magnet. the field lines are closed curves, they emerge from the north pole and merge in the south pole outside the magnet and inside the direction is from south to north. inside the solenoid and a bar magnet the field is uniform

Answer 2

Answer:

2) 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
