When a coil of cross-sectional area A and number of turns N is rotated in a uniform magnetic field B with angular velocity ω, then the maximum emf induced in the coil will be
Correct answer: C. BNAω
- A. BNA
- B. Baω/N
- C. BNAω
- D. Zero
Explanation
As ε=NωABsin0 For maximum induced ε=NωAB

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.

Two different loops are concentric and lie in the same plane. The current in the Outer loop is clockwise and increasing with time. The induced current in the inner loop then, is:
As shown in the figure, a magnet is moved with a fast speed towards a coil at rest. Due to this induced electromotive force, induced current and induced charge in the coil is E, I and Q respectively. If the speed of the magnet is doubled, the incorrect statement.
To induce an emf in a coil the linking magnetic flux:
