Question

Consider a circular wire loop of radius R spinning about a diametrical chord which is perpendicular to a uniform magnetic field $(\vec{B}=B_0 \hat{k})$

• A. The magnitude of the induced EMF in the loop is maximum when the plane of the loop is perpendicular to $\vec{B}$
• B. Flux through the loop is minimum when the plane of the loop is perpendicular to $\vec{B}$
• C. The direction of induced current remains same during the spinning motion of the loop
• D. EMF induced will be the same for a larger radius of the loop in the same field
• E. No EMF will be induced since magnetic field is constant

Hint:

EMF depends on rate of change of flux, not just flux value.

Answer 1

The Correct Option is A
