Textbook Question
Chapter 20, Problem 9MCP
A metal bar connected by metal leads to the terminals of a battery hangs between the poles of a horseshoe magnet, as shown in Figure 20.53. Just after the switch S is closed, what will happen to the bar? (Hint: Recall that magnetic field lines point out of a north magnetic pole and into a south magnetic pole.)
Figure 20.53
Multiple-Choice Problem 9.
- A. It will be pushed upward, decreasing the tension in the leads.
- B. It will be pushed downward, increasing the tension in the leads.
- C. It will swing outward, away from the magnet.
- D. It will swing inward, into the magnet.
