A circular coil having mass m is kept above the ground (x-z plane) at show height . Coil carries a curretn i in the direaction shown is figure. In which direaction a unifrom magnetic field B be applied so that the magnetic force balances the weight of the coil

A

Positive x-direction

B

Negative x-direction

C

Positive z-direction

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
d
Net force on a current carrying loop in a uniform magnetic field is zero. So, magnetic force cannot balance its weight.
