MHT CET · Physics · Magnetic Effects of Current
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 & Solution
Correct Answer
(C) radius of the toroidal solenoid.
Step-by-step Solution
Detailed explanation
Magnetic induction along the axis of toroidal solenoid is given by
\(B=\mu_0 n I \quad n=\frac{N}{2 \pi r}\)
\(\mu_0=\) permeability
\(\mathrm{n}=\) Number of turns per unit length
\(\mathrm{I}=\) Current passing through it
Hence magnetic induction does not depend on radius of toroidal solenoid.
\(B=\mu_0 n I \quad n=\frac{N}{2 \pi r}\)
\(\mu_0=\) permeability
\(\mathrm{n}=\) Number of turns per unit length
\(\mathrm{I}=\) Current passing through it
Hence magnetic induction does not depend on radius of toroidal solenoid.
