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
  • ✓
    Equal
  • C
    Can be different or equal depend upon material
  • D
    Can't say
✓

Answer

Correct option: B.
Equal
potential energy in magnetic feild is given by $U = \mu B \sin \ \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.
