Question

A rectangular coil of wire 100 turns and 100 x 15cm2 size carrying a current of 2Amp.is in a magnetic field of induction 2*10^3wb/m^2

Answer 1

Answer:

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 (plz comment me)
