Answer:
67.44 V
Explanation:
Number of turns N =123
Radius = 2.41 cm =0.0241 m
The magnetic field strength increases from 50.9 T to 96.3 T so change in magnetic field dB = 96.3-50.9=45.4 T
Time interval dt = 0.151 sec
We know that the induced emf [tex]e=-NA\frac{dB}{dt}[/tex]
Area [tex]A=\pi r^2=3.14\times 0.0241^2=1.8237\times 10^{-3}m^2[/tex]
Putting all these values in emf equation [tex]e=-123\times 1.8237\times 10^{-3}\times \frac{45.4}{0.151}=-67.44\ V[/tex] here negative sign indicates that it opposes the cause due to which it is produced
