The magnetic induction due to an ideal solenoid is independent of (a) total number of turns of the wire. (b) length of the solenoid. (c) radius of the wire. (d) current carried by the wire.

Answer: (c). For an ideal solenoid B = (μ₀ N I)/(L). It depends on total turns N, length L and current I. It does not depend on the radius of the wire. So the answer is (c).

The magnetic induction due to an ideal solenoid is independent of

Show answer and solution

Answer: (c)

For an ideal solenoid $B = \dfrac{\mu_0 N I}{L}$ .
It depends on total turns $N$ , length $L$ and current $I$ .
It does not depend on the radius of the wire.
So the answer is (c).
