By following Lenz's Law, which says that the induced electrical force works against any change in magnetic flux the correct answer to the direction of the induced EMFs in loops A, B, C, and D is counterclockwise (CCW), clockwise (CW), CW, and CCW is : option c . CCW, CW, CW, CCW
By following Lenz's Law we can figure out the direction of the induced forces in the four loops. can figure out :
Loop A (Top-left): The loop is approaching the wire with the current. The induced force opposes this movement, so it goes counterclockwise (CCW).
Loop B (Top-right): The loop is moving away from the wire. The induced force supports this movement, so it goes clockwise (CW).
Loop C (Bottom-right): Similar to Loop B, the loop is moving away from the wire, so the induced force is clockwise (CW).
Loop D (Bottom-left): The loop is approaching the wire. The induced force opposes this movement, so it goes counterclockwise (CCW).
So, the correct answer is: option c . CCW, CW, CW, CCW
The complete question
Four loop are moving relative to a wire carrying a constant current to the right as shown

a. CW, CCW, CCW, CW
b. CCW, CCW, CW, CW
c. CCW, CW, CW, CCW
d. CW, CW, CCW, CCW
