Question

A circular coil of 30 turns and radius 8.0 cm carrying a current of 6.0 A is suspended vertically in a uniform horizontal magnetic field of magnitude 1.0 T. The field lines make an angle of 60° with the normal of the coil. Calculate the magnitude of the counter torque that must be applied to prevent the coil from turning.Would your answer change, if the circular coil in (a) were replaced by a planar coil of some irregular shape that encloses the same area? (All other particulars are also unaltered.)

Answer 1

Answer:

Given- π6∆©

so,

A circular coil having 100 turns radius 10 cm carries a current of 5a. It is suspended vertically in a uniform horizontal magnetic field of 0.5 t the field lines making an angle of 60degree with the plane of the coil

Answer 2

Answer:

It will be a circular coil
