permeability
Solution
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.
