A square wire loop having side length , mass , and resistance is moving along the positive -axis at a speed of . It enters a uniform, steady magnetic field at seconds, as shown in the figure.
Find the total amount of heat loss in the resistance.
Details and Assumptions:
The magnitude of is sufficient that the loop comes out of the region of magnetic field with some speed.
Neglect any type of energy loss other than the heat loss in resistance of the wires of the square.
Take .
