Answer:
0.00479 volts
Explanation:
From Faraday's law of electromagnetic induction, the induced emf equals the change in magnitude flux (magnetic field strength multiplied by the area = BA) divided by the time change
Therefore we have the equation
EMF = BA÷t
Since area A = 2πr
EMF = Bπr²÷t
B = 5.5×10^(-5)
Velocity = 100km/h = 27.7778m/s
r = 1m, t = r÷V = 0.036
EMF = Bπr²÷t = (5.5×10^(-5) x π x (1)²)÷0.036 = 0.00479 Volts
