Question 3A circular loop placed in a plane perpendicular to the plane or paper carries a current when the key is ON. The current as seen from points A and B (in the plane of paper and on the axis of the coil) is anticlockwise and clockwise respectively. The magnetic field lines point from B to A. The N-pole or the resultant magnet is on the race close to(a) A(b) B(c) A if the current is small, and B if the current is large(d) B if the current is small and A if the current is large |
