Answer:
4.875 V
Explanation:
N = 1300
diameter = 2.10 cm
radius = half of diameter = 1.05 cm
B1 = 0.130 T
B2 = 0 T
t = 12 ms
According to the law of electromagnetic induction,
[tex]e = - N\frac{d\phi }{dt}[/tex]
Where, Ф be the magnetic flux linked with the coil
[tex]e = - NA \frac{dB }{dt}[/tex]
[tex]e = -1300\times3.14\times{1.05\times 1.05\times 10^{-4}\times\frac{0-0.130}{12\times10^{-3}}=[/tex]
e = 4.875 V
