The magnetic induction along the axis of a toroidal solenoid is independent of (a) number of turns per unit length. (b) current passing through it. (c) radius of the toroidal solenoid. (d) permeability

Answer: (c). Inside a toroid B = μ n I with n = (N)/(2π r) turns per unit length. Written in terms of n, B depends on n, I and μ only. So the answer is (c) radius of the toroidal solenoid.

The magnetic induction along the axis of a toroidal solenoid is independent of

Show answer and solution

Answer: (c)

Inside a toroid $B = \mu n I$ with $n = \dfrac{N}{2\pi r}$ turns per unit length.
Written in terms of $n$ , $B$ depends on $n$ , $I$ and $\mu$ only.
So the answer is (c) radius of the toroidal solenoid.
