A magnetic field is changing at a rate of 3500 times 103 Wbs
     A magnetic field is changing at a rate of 3500 times 10^-3 Wb/s. How much voltage is induced across a 50 turn coil that is placed in the magnetic field? 
  
  Solution
V=n(d/dt)
n=50
d/dt = 3500x10^-3 Wb/s
V=50x3500x10^-3=175 Volt
Voltage induced in 50 turn coil is 175 Volts
