A circular coil having mass m is kept above ground (x-z plane) at some height. The coil carries i in the direction shown in Fig. 1.143. In which direction a uniform magnetic field `vec 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.
