1) A 10-ohm light bulb is connected across two long straight conducting rails that are separated by 1m. A straight conductor is placed perpendicular across the rails. A 0.4 Tesla magnetic field points perpendicular to both the rails and the conductor.

a) What is the magnitude and direction of the current in the conductor when it is sitting still?

b) What is the magnitude and direction of the current in the conductor when it is moving to the right with a velocity of 2m/s?

c) What is the magnitude and direction of the current in the conductor when it is moving to the left with a velocity of 4m/s?

2) An ideal transform consists of a primary coil of 120 turns and a secondary of 8 turns. A 1000W 120V rms voltage is applied to the primary.

a) What is the voltage in the secondary?

b) What is the power out of the secondary?

c) What is the current in the primary?

d) What is the current in the secondary?
