The magnetic field inside a solenoid is-

A

increases from one end to another

B

zero at the middle

C

varies from point to point

D

uniform

Text Solution

Verified by Experts

The correct Answer is:
D
The magnetic field inside a solenoid is proportional to the current, number of turns and inversely proportional to length. so , there is no direct relationship between the position of the solenoid and the magnetic field, so the magnetic field inside the solenoid is uniform throughout
