An electron moving with a speed of 4.3×105 m/s in the positive x direction experiences zero magnetic force. When it moves in the positive y direction, it experiences a force of 3.9×10−13 N that points in the positive z direction.
1. What is the direction of the magnetic field?
2. What is the magnitude of the magnetic field?
