RE Albert's laboratory is filled with a constant uniform magnetic field pointing straight up. Albert throws some charges into this magnetic field. He throws the charges in different directions, and observes the resulting magnetic forces on them. Given the sign of each charge and the direction of its velocity, determine the direction of the magnetic force (if any) acting on the charge. Resulting magnetic force Positive charge moving south: Negative charge moving west: Negative charge not moving at all: ....
