Document Summary
Please read the problems carefully and answer them in the space provided. Write on the back of the page, if necessary. Problem 1 (10 pts, answer for each part is correct or incorrect - 2 pts/part ): (a) an electron moves in the direction shown into a uniform magnetic field. B (b) consider the two coaxial circular conducting loops shown below. X x x x x x e- in the left loop that is decreasing in magnitude with time. Indicate the direction (if any) of the current in right loop. Write "zero" if there is no current in the second loop. (c) a positive charge moves as shown in a uniform magnetic field. Clearly indicate on the sketch the direction of the force (if any) on the electron. V (d) a conducting rod with no net charge is spinning in a uniform magnetic field around an axis through one end as shown below.
