Problem 55P

· CE A loop of wire is connected to the terminals of a battery, as indicated in Figure 22–41. If the loop is to attract the bar magnet, which of the terminals, A or B, should be the positive terminal of the battery? Explain.

FIGURE 22–41

Step-by-Step Solution:

Solution 55 P:

Step 1 of 1:-

Here, we have to explain which of the terminal will be the positive terminal of the battery.

The magnetic field lines are passing through the wire loop.

In order to oppose the change in magnetic flux through the area of the loop, there will be a flow of current in the wire loop. The current will be in such a direction that will oppose the change in magnetic field. The magnetic field created by the wire loop will be in the opposite direction of the magnetic field of the bar magnet.

As, the current flows from positive end to negative end, the terminal A will be positive.
