Solution

Generation of an alternating e.m.f. by a loop of wire rotating in a magnetic field

Expression of the instantaneous value of the induced e.m.f. in a rotating loop

ε = NBAω sinωt

Where N = number of turns in armature coil

= Magnetic field vector

=Area vector of the coil

ω Angular speed

Concept: Electromagnetic Induction
