The north-pole end of a bar magnet is held near a positively charged piece of plastic. The plastic is 1 2 3 33% 33% 33% 1 2 3 4 5 1. attracted 2. repelled 3. unaffected by the magnet
The magnetic force exerted by a magnetic field on a charge is proportional to the charge’s velocity relative to the field. If the charge is stationary, as in this situation, there is no magnetic force.

An electron moves in the plane of this paper toward the top of the page. A magnetic field is also in the plane of the page and directed toward the right. The direction of the magnetic force on the electron is 1 2 3 4 5 6 17% 17% 17% 17% 17% 17% 1 2 3 4 5 1. toward the top of the page 2. toward the bottom of the page 3. toward the left edge of the page 4. toward the right edge of the page 5. upward out of the page 6. downward into the page
The right-hand rule gives the direction. Be sure to account for the negative charge on the electron.
