A rectangular metallic loop with sides L, and L, is placed in the vertical plane, making an angle op with
respect to the x-axis, as shown in the figure, and a spatially uniform magnetic field B = By is applied. The
loop is free to rotate about the axis (shown in the figure with a double line). The magnetic field changes
with time at a constant rate
