Marks: +1, -0

Consider a circular wire loop of radius R spinning about a diametrical chord which is perpendicular to a uniform magnetic field (

→

=B0

⋀

)

The magnitude of the induced EMF in the loop is maximum when the plane of the loop is perpendicular to
→
B
Flux through the loop is minimum when the plane of the loop is perpendicular to
→
B
The direction of induced current remains same during the spinning motion of the loop
EMF induced will be the same for a larger radius of the loop in the same field
No EMF will be induced since magnetic field is constant
