The free space inside a current carrying toroid is filled with a material of susceptibility 2 x 10 -2 . The percentage increase in the value of magnetic field inside the toroid will be
Text Solution
Verified by ExpertsThe correct answer is:
C
It is given that
= 2 x 10 -2
The permeability is
= 1 + 
= 1 + 0. 02 = 1. 02.
The magnetic field is 
Hence, percentage increase in magnetic field is
