MCQ
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. Equal

Explanation:

potential energy in magnetic feild is given by U = μB sinθ 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.
