Question

A 100 turn closely wound circular coil of radius 10 cm carries a current of 3.2 A. (a) What is the field at the centre of the coil? (b) What is the magnetic moment of this coil?

Answer 1

Answer:

A 100 turn closely wound circular coil of radius 10 cm carries a current of 3.2 A .The coil has a moment of inertia 0.1 kg (m)^2. The coil is placed in a vertical plane and is free to rotate about a horizantal axis which coincies with its diameter
