A circular conducting loop of radius 23.0 cm is located in a
region of homogeneous magnetic field of magnitude 0.500 T pointing
perpendicular to the plane of the loop. The loop is connected in
series with a resistor of 167 Ω. The magnetic field is now
increased at a constant rate by a factor of 2.20 in 19.0s.
1.Calculate the magnitude of the induced emf in the loop while the
magnetic field is increasing.
2.Calculate the magnitude of the current induced in the loop while
the field is increasing.
3.With the magnetic field held constant at its new value of 1.10 T,
calculate the magnitude of the average induced voltage in the loop
while it is pulled horizontally out of the magnetic field region
during a time interval of 7.50 s.
given
dB/dt = (2.20-0.5)/19 = 0.089 T/s
Area of loop = A = r2 =
(0.23)2 = 0.166 m2
1) induce emf = E = A dB/dt
E = 0.166 x 0.089 = 0.014 volts
2) as resistance =R = 167 ohm
so so current i = E/R = 0.014 / 167 = 0.088 mA
3) now dB/dt = (1.10 -0.5)/7.5 = 0.08 T/s
so emf = A dB/dt = 0.166 x 0.08 = 0.013 volts
so current i = 0.013 / 167 = 0.079 mA
