Question

A ring of radius 10 cm carrying current 2A
placed in horizontal plane in uniform magnetic
field in such a way, that field makes an angle
30° with vertical direction. Magnitude of
magnetic field at each point of ring is 350G,
magnetic force on ring is :-​

Answer 1

Answer:

Explanation:

= 100, i = 3.2 A and r = 10 cm = 0.1 m
