- #17-aoutside the toroid, (b) inside the core of the toroid, and (c) in the empty space surrounded by the toroid.Ans : Magnetic field outside a toroid is zero. It is non-zero only inside the core of a toroid.
(b) Magnetic field inside the core of a toroid is given by the relation,
B =
Where,
= Permeability of free space = .gif)
l = length of toroid

(c) Magnetic field in the empty space surrounded by the toroid is zero.
