1. A bar magnet is spinning clockwise as viewed from a position south of the magnet, about a horizontal, north-south axis that is perpendicular to, and passes through the center of, the bar magnet. What is the direction of the electric field, if any, directly above the magnet at an instant when the magnet is vertical with its north end up? a) Northwarde) Upward b) Southwardf) Downward c) Eastwardg) There is no electric field. d) Westwardh) None of the above.

2. A tiny lead pellet having a negative charge is falling toward the ground. In the rest frame of the ground, what is the direction of the magnetic field, if any, due to the falling particle? a) Northwarde) Upward b) Southwardf) Downward c) Eastwardg) There is no magnetic field. d) Westwardh) None of the above.

3. A horizontal loop carries a current that is clockwise as viewed from above, but, the loop is rotating counterclockwise as viewed from above. What is the direction of the electric field, if any, due to the rotating loop at a point at the same elevation as, and due north of, the loop. a) Northwarde) Upward b) Southwardf) Downward c) Eastwardg) There is no electric field. d) Westwardh) None of the above.

4. A positively charged particle is moving northward, directly toward point P.
