The figure(Figure 1) shows two strong magnets on opposite sides of a small table

Question

The figure(Figure 1) shows two strong magnets on opposite sides of a small table. The long-range attractive force between the magnets keeps the lower magnet in place.

Part A

Draw free-body diagram for the upper magnet. Draw the vectors starting at the black dot. The location and orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.

Part B

Draw free-body diagram for the table. Draw the vectors starting at the black dot. The location and orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.

Part C

Draw free-body diagram for the lower magnet.

Draw the vectors starting at the black dot. The location and orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.

Part D

Suppose the weight of the table is 23 N , the weight of each magnet is 2.0 N , and the magnetic force on the lower magnet is three times its weight. Find the magnitude of each of the forces shown on your free-body diagram for the upper magnet.

Explanation / Answer

The force of the lower magnet on the upper magnet and vice versa will be equal in magnitude and opposite in direction.

By Newton's Third Law,

The magnitude of the force on the lower magnet is ,

F=3* 2 N

=6 N

The direction of the magnetic force on the lower magnet is upward, toward the upper magnet. Conversely, the magnetic force of the lower magnet on the upper magnet will be downward, also with a magnitude of 6N .
