The magnetic field inside the solenoid in the figure changes at the rate of 4.5 T/s. A conducting coil with 2000 turns surrounds the solenoid, as shown. The radius of the solenoid is 5 cm, and the radius of the coil is 8 cm. What is the potential difference induced in the coil?
Homework Answers
Here ,
for the solenoid ,
number of turns = 2000 per meter
as dB/dt = 4.5 T/s
NOw , induced emf = rate of change of flux
EMF = 2000 * pi*0.05^2 * 4.5
EMF = 70.7 V
the induced potential difference is 70.7 V
