Question

Question 4: A solenoid is a long tube wrapped in a current carrying wire as depicted in the figure below. The current in the solenoid is constant (lo). A small square loop with a. side length b is placed in the center of the solenoid, as shown below: Solenoid with small loop inside Note that the Area vector for this loop is shown for you at the instant given. The loop is rotating so that the area vector rotates clockwise with an angular acceleration . At t = 0, the loop is oriented vertically and omega0 = 0. a) Indicate the direction of the in(ince(i current in the 1001) when the area vector is pointing to 3 o'clock, 6 o'clock, 9 o'clock, and 12 o' clock by placing a ''dot'' or a ''cross'' in each circle. If the current is zero, state that explicitly.

Explanation / Answer

The magnetic field of the coil is from left to right.

Looking the square loop from right to left, the induced current will be:

3 o'clock: The magnetic flux is being incresed, hence the current will be clockwise.

6 o'clock: The magnetic flux is 0, The current is 0.

9 o'clock: The magnetic flux is maximum, but counterclockwise this time.

12 o'clock: The magnetic flux is 0 again.
