Question

Two current carrying loops of same area but of different materials have same current flowing in them in anti-clockwise direction. if a magnetic field is applied in upward direction then potential energy of loop 1 and loop 2 will always be:

• A. Different
• B. Equal
• C. Can be different or equal depend upon material
• D. Can't say

Answer 1

The correct option is B Equal

potential energy in magnetic feild is given by $U=\mu Bsin\theta$ Two current carrying loops of same area but of different materials have same current flowing in them in anti-clockwise direction.if a magnetic field is applied in upward direction then potential energy of loop 1 and loop 2 will always be Equal
