Question

2. Field inside a solenoid is :
(a) directly proportional to its length
(b) directly proportional to current
(c) inversely proportional to number of turns
(d) inversely proportional to current.​

Answer 1

Explanation:

The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length. There is no dependence on the diameter of the solenoid, and the field strength doesn't depend on the position inside the solenoid, i.e., the field inside is constant.
