A coil is rotated in a uniform magnetic field about an axis perpendicular to the field. The emf induced in the coil would be maximum when the plane of the coil is
Correct answer: C. perpendicular to the field
- A. parallel to the field
- B. at 45° to the field
- C. perpendicular to the field
- D. none of them
Explanation
C is the correct answer.The emf induced in a coil rotating in a uniform magnetic field is maximum when the plane of the coil is perpendicular to the field. This is in accordance with Faraday's law of electromagnetic induction.

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.
