Two lines of force due to a bar magnet
Intersect at the neutral point
Intersect near the poles of the magnet
Intersect on the equatorial axis of the magnet
Do not intersect at all
The current is flowing through solenoid, then solenoid acting as what ?

A long magnet is cut in two parts in such a way that the ratio of their lengths is $ 2 : 1. $ The ratio of pole strengths of both the section is
Magnetic induction is a
A magnetic needle suspended horizontally by an unspun silk fibre, oscillates in the horizontal plane because of the restoring force originating mainly from
