Question

A solenoid is filled with material of susceptibility 2 x 10^-7 Fractional change in field intensity compared to the case when air was present inside instead of material

(a) = 2 x 10^-5%

(b) = 4 x 10^-5%

(c) = 3 x 10^-5%

(d) = 5 x 10^-5%

Answer 1

Correct option is (a) = 2 x 10^-5%

It is already fractional change in the magnetic induction due to the medium.

∴ % age change
