A rectangular loop of wire is placed perpendicular to a uniform magnetic field and then spun around one of its sides at frequency "P".The induced emf is maximum when:
Correct answer: A. The flux is zero
- A. The flux is zero
- B. The flux is maximum
- C. The flux is half its maximum value
- D. The derivative of the flux with respect to time is zero
Explanation
When the magnetic flux through the rectangular loop is zero the emf is maximum.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
