14. A circular loop placed in a planeperpendicular to the plane of paper carriesa current when the key is ON. The currentas seen from points A and B (in the planeof paper and on the axis of the coil) is anticlockwise and clockwise respectively. Themagnetic field lines point from B to A. TheN-pole of the resultant magnet is on the faceclose toVariableresistance(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 largeir

Answer»

the answer is AMisconception is that magnetic field lines point from north to south pole. The fact is that they emerge out of North pole and entre into South pole.
