Question

Problem 2 : A figure shows a square loop of wire of side L = 0.25m and resistance R = 0.2 ohms. A constant magnetic field B1 points through the left half of the loop in the negative z direction and has magnitude B1 = 3T. A different magnetic field B2 points through the right half of the loop in the positive z direction and has magnitude B2 = 5T. The loop is being pulled to the left with velocity of magnitude v = 3 m/s . All questions below relate to the moment when the boundary between the fields is in the middle of the loop.

Question 1 : What is total flux (with positive outward) through the loop?

Question 2 : What is rate of change in flux through the loop?

Question 3 : What is current I (with positive counterclockwise) in the loop?

Question 4 : What is the x-component of the force FRx on the right side of the loop?

Question 5 : What is the x-component of the force FLx on the left side of the loop?
