Multiple Choice Questions (5 points per question, Bubble sheet). 1) The current in a wire along the x axis flows in the positive x direction. If a proton, located as shown in the figure, has an initial velocity in the positive z direction, it experiences e) no force. 2) If you assume that the scalings of the axes of these h curves are the same, you can conclude that ysteresis b) curve 2 is for a magnetically soft material. 3) A long solenoid with 20 turns per centimeter has a core of iron-silicon. When the current is 1.50 A, the magnetic field inside the core is 4.50 T. The magnetization M is approximately

Unformatted text preview: a) 3.58 x 10 6 A/m 4) Two parallel wires carry currents I 1 and I 2 = 2 I 1 in the same direction. Which of the following expressions shows the relationship of the forces on the wires? a) F 1 = F 2 5) A square loop of wire moves with constant speed v. It enters and later leaves a region of uniform magnetic field pointing into the paper, as shown (the loop is smaller than the region with the field). Which of the five graphs below correctly shows the induced current in the loop as a function of time? Take clockwise current as positive. 1...
