Three conducting loops are situated side-by-side in the plane of the page. A clockwise current flows in the center loop B, and its magnitude is decreasing in time. The induced currents in loops
A and C:
A) flow in opposite directions,A clockwise, B counterclockwise)
b)both flow counterclockwise
C)both flow clockwise
D) flow in opposite directions (A counterclockwise, B clockwise
well, A is not the answer, I was thinking about C, but I'm not sure
by the way, have you done the 4th questions?
To determine the direction of the induced currents in loops A and C, you can use Lenz's Law. Lenz's Law states that the direction of an induced current is such that it opposes the change that produced it.
In this case, the current in loop B is decreasing. According to Lenz's Law, the induced currents in loops A and C will try to oppose this decrease.
For loop A, if the induced current flows counterclockwise (opposite to the clockwise current in loop B), it would create a magnetic field that opposes the decrease in current in loop B. Therefore, loop A will have an induced current flowing counterclockwise.
For loop C, if the induced current flows clockwise (same direction as the clockwise current in loop B), it would also create a magnetic field that opposes the decrease in current in loop B. Therefore, loop C will have an induced current flowing clockwise.
So, the correct answer is:
A) The induced currents in loops A and C flow in opposite directions, with A flowing counterclockwise and C flowing clockwise.
