1)

A current-carrying coil is subjected to a uniform magnetic field. The coil will orient so that its plane becomes


A) inclined at 45° to the magnetic field

B) inclined at any arbitrary angle to the magnetic field

C) parallel to the magnetic field

D) perpendicular to the magnetic field

Answer:

Option D

Explanation:

A current-carrying coil behaves as a magnetic dipole. Therefore, in a uniform magnetic field coil will get aligned such that the dipole moment of the coil is parallel to the magnetic field. And we know that the dipole moment of a coil is perpendicular to its plane.

Therefore, coil will align itself such that its plane is perpendicular to the direction of the magnetic field.
