MHT CET 2026 Physics question
The magnetic induction produced inside an ideal solenoid, depends on which of the following quantities ? (a) number of turns per unit length. (b) radius of the wire. (c) current flowing through it. (d) permeability of the medium.
Answer: (D)
Solution
Inside a long ideal solenoid the field is uniform and given by , where is the permeability of the medium (core), the number of turns per unit length and the current. Hence depends on (a) turns per unit length, (c)
