Question

In the figure shown, the magnet is first withdrawn upward from the loop of wire, then moved downward toward the loop of wire. As viewed from above, the induced current for both cases clockwise with increasing magnitude. for both cases counterclockwise with increasing magnitude first clockwise, then counter-clockwise for both cases clockwise with decreasing magnitude for both cases counterclockwise with decreasing magnitude first counter-clockwise, then clockwise. Consider a loop of wire with a resistor. In the same plane, (with switch S closed) a long wire has a current I flowing from left to right. If switch S is closed for a long period of time, and then suddenly opened, what is the direction of the induced current through R as the current I rapidly decreases? There is no current flow. The current flows right to left through The current flows left to right through R.

Explanation / Answer

question 13:

6. first counter clockwise then clockwise

question 14:

the current flows left to right through R
