A uniform resistance wire of resistance 10 ohm is in a form of circular loop. Two points A and B on this loop are connected to a source of e.m.f. 5 volt. If the two segments are in the ratio of 2 : 3, the magentic field intensity at the centre of the loop is
5`pi` Wb / m2
3`pi` Wb / m2
`pi//3` Wb / m2
zero
