Physics Electromagnetic Induction Mix MCQ (Single Correct)

A loop is kept so that its center lies at the origin of the coordinate system. A magnetic field has the induction B pointing along Z axis as shown in the figure

A
No emf and current will be induced in the loop if it rotates about Z axis
B
Emf is induced but no current flows if the loop is a fiber when it rotates about y axis.
C
Emf is induced and induced current flows in the loop if the loop is made of copper
D
If the loop moves along Z axis with constant velocity, no current flows in it.

The correct answer is:
CHECK THE SOLUTION.

(a, b, c, d)

If the loop rotates about Z axis, the variation of flux linkage will be zero. Therefore no emf is induced. Consequently no current flows in the loop When it rotates about y axis, its flux linkage changes. Therefore an emf is induced. Since the loop is a fiber it is not conducting (very high electrical resistance). Therefore induced current is zero.

If the loop is made of copper, it is conductive therefore induced current is set up.

If the loop moves along the Z axis variation of flux linkage is zero. Therefore the induced emf and current will be equal to zero.
