6. The moving rod in the figure is 30.0 cm long and moves with a speed of 25.0 cm/s. If the magnetic field is uniform with a magnitude of 0.45 T, and the resistance of the circuit is 40.0 , a) what is the induced current in the rod? 7. b) What is the direction of the induced current in the circuit? Counterclockwise OClockwise

Explanation / Answer

L = 0.3 m

V = 0.25 m/s

E = B*L*V

E = 0.45*0.3*0.25 = 0.03375 Volt

volt = I*R

I = 0.03375 / 40 = 8.437*10-4 Amp clockwise
