Question:

A very thin 18.0 cm copper bar is aligned horizontally along the east-west direction.?

A. If it moves horizontally from south to north at 13.0 m/s in a vertically upward magnetic field of 1.28 T, what potential difference is induced across its ends ?B.If it moves horizontally from south to north at 13.0 m/s in a vertically upward magnetic field of 1.28 T , which end (east or west) is at a higher potential ?C.What would be the potential difference if the bar moved from east to west instead?

Answer:

Birth control. No, seriously. It kills sperm.
EMF VLBcos(theta) Theta - the angle between the direction of motion and the direction of the magnetic field V - speed in m/s L - length in meters B - magnetic field in teslas Plug and chug
Money, wiring and to catch criminals! ;)
