A circular wire loop of radius r = 0.35 m and resistance R = 8.2 Ω rotates about a shaft through its diameter at a constant rate of f = 5.35 Hz in a uniform B = 0.27 T magnetic field directed perpendicular to the rotation axis. The plane of the loop is perpendicular to the magnetic field at time t = 0.
Find the value of the magnetic flux through the loop, in webers, at time t = 0.123 s.
Calculate the induced emf in the loop, in volts, at time t = 0.123 s.
Find the induced current in the loop, in amperes, at time t = 0.123 s.
