STANDARD Physics Induced EMF MCQ Question
A rectangular, a square, a circular and an elliptical loop, all in the (x – y) plane, are moving out of a uniform magnetic field with a constant velocity, v = v î. The magnetic field is directed along the negative z axis direction. The induced emf, during the passage of these loops, out of the filed region, will not remain constant for
The circular and the elliptical loops.
Only the elliptical loop.
Any of the four loops.
The rectangular, circular and elliptical loops.
Correct Answer
Detailed Explanation
When the loops are being drawn out of the field, the rate at which the number of field lines cutting through the loop decreases will be a constant for square and rectangle loops, but not for circular or elliptical shapes.
