A generator consists of 10.0 turns of wire, and each turn has an area of 0.095 m2. If a maximum emf of 1.2 x 102 V is induced when the coil rotates with a frequency of 60.0 Hz, what is the strength of the magnetic field

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
