23. A current carrying coil is subjected to a uniform magnetic field. The coil will orient so that its plane becomes
[1988]
(a) inclined at $45^{\circ}$ 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
Show Answer
