Rotate the coil about the y-axis.

Rotate the coil about the x-axis.

Change the current in the solenoid.

Rotate the coil about the z-axis.

Move the coil toward point P.

Rotate the coil about the y-axis.

Rotate the coil about the x-axis.

Change the current in the solenoid.

Rotate the coil about the z-axis.

Move the coil toward point P.

Explanation / Answer
