A current carrying coil is subjected to a uniform magnetic field. The coil will orient so that its plane becomes
- inclined at \( 45^\circ \) to the magnetic field
- inclined at any arbitrary angle to the magnetic field
- parallel to the magnetic field
- perpendicular to the magnetic field
Correct answer: perpendicular to the magnetic field
Solution
A current-carrying coil in a uniform magnetic field experiences a torque that tends to align its plane perpendicular to the magnetic field to minimize potential energy.
