Question

Even if the net force zero on the coil placed in a magnetic field, the coil still rotates, Why ? Imagine

& Write.​

Answer 1

Answer:

A current carrying loop in a uniform magnetic field will experience torque only given by

τ

=

M

×

B

Where M is magnetic moment of loop B is magnetic field.

Force is zero on a current carrying loop in a uniform magnetic field.

Note : Magnetic field must be uniform for net force to be zero.

For a non uniform field, net force may not be zero
