A circular coil has moment ofinertia 0.8 kg m² around any diameter and is carrying current to produce a magnetic moment of 20 Am². The coil is kept initially in a vertical position and it can rotate freely around a horizontal diameter. When a uniform magnetic field of 4 T is applied along the vertical, it starts rotating around its horizontal diameter. The angular speed the coil acquires after rotating by 60° will be: (a) 10 rad s-! (c) 20n rad s-! (b) 10л гad s I (d) 20 rad s-!
