1. Determine the force on a horizontal conductor 5.00cm long and carrying 30.0A from south to north if placed in a horizontal magnetic field of flux density 8.00 x 10^-1 T directed from east to west.
2. The horizontal component of the Earth's magnetic field at the equator is 3.0 x 10^-5T. What length of wire carrying 0.25A in an east-west direction would experience a vertical force of 3.0 x 10^-6N?
3. A horizontal wire is aligned in a N-S direction and a compass needle is placed below the wire. When the current is switched on, the N pole of the compass needle deflects towards the east. In which direction are the electrons in the wire moving? Explain your answer.
