The induced e.m.f in a coil rotating in a uniform magnetic field will increases if

A. Total number of turns in the coil decreases
B. Magnetic field increases
C. Speed of rotation of coil decreases
D. Area of the coil increases

Choose the correct answer from the options given below:

A, B, C and D Only

induced e.m.f for a coil of wire depends on four things:

1. Magnetic strength of the core in the coil of wire. 

2. Number of turns of wire in the coil

3. The cross-sectional area of the coil

4. How fast you move the magnet into/out of the coil.
