Ques. 1JEE Main 2025, 2 April (Morning Shift)

The relationship between the magnetic susceptibility ( ) and the magnetic permeability ( ) is given by : ( 0 is the permeability of free space and r is relative permeability)

= 0 - 1
= r 0 + 1
= r + 1
= 1 - 0

Answer

(1) = 0 - 1

Solution

B = 0(H + M) = 0(1 + )H

Also B = H

= 0(1 + )

r = 0 = 1 +

= 0 - 1

Answer: (1)
