Question

A rectangular coil carrying current is placed in a uniform magnetic field in such a way that normal to the plane of the coil makes an angle 0 with the direction of magnetic flux density . Find the magnitude of torque acting on the coil

Answer 1

Answer:

τ

=

M

×

B

=niABsinθ

So, for torque to be zero sinθ should be zero and for that θ should be zero, where θ is angle between normal to the plane of coil and field.

So the plane of the coil and field should be perpendicular to each other
