Bar Magnet: Practice Problem & Solution

A coil carrying electric current is placed in uniform magnetic field: (1993)
Torque is formed
e.m.f is induced
Both (a) and (b) are correct
None of these

Solution Explained:

To solve this problem, we apply the core principles of Bar Magnet. Understanding the underlying formula is key to arriving at the correct answer below:

A current-carrying coil placed in a uniform magnetic field experiences a magnetic torque. No e.m.f. is induced as the magnetic flux linked with the stationary coil remains constant.
