State the factors on which induced e.m.f. in a coil rotating in a uniform magnetic field depends.

Derivea expression for inducede.m.f. whenacoilrotates in a uniform magnetic field andprove it graphically that the e.m.f. induced is alternating in nature.

state the rule to determine the direction of a current induced in a coil due to its rotation in a magnetic field.

What is electromagnetic induction ? State its Faraday's laws. Find an expression for the e.m.f. induced due to change in the area of a coil lying in a uniform magnetic field.

How does induced e.m.f. depend upon the change in magnetic flux?
