Question

A metallic loop is placed in a uniform magnetic fileld vecB with the plane of the loop perpendicular to vecB. Under which condition(s) given below an emf will be induced in the loop ? "If the loop is ......." (A) moved along the direction of vecB (B) squeezed to a smaller area (C) rotated about its axis (D) rotated about one of its diameters

If moved along vecB or rotated about its own axis, flux remains unchanged.

Q. A metallic loop is placed in a uniform magnetic fileld $B$ with the plane of the loop perpendicular to $B$ . Under which condition(s) given below an emf will be induced in the loop ?

moved along the direction of $B$

squeezed to a smaller area

rotated about its axis

rotated about one of its diameters
