A rigid planar triangular conducting loop of resistance \(R\) enters a region of uniform magnetic field perpendicular to the loop at a constant velocity \(v\), entering vertex-first at time \(t = 0\). The loop becomes completely immersed in the field at time \(t_1\) and remains entirely within the field until after time \(t_2\). The graph shows the magnetic flux \(\Phi_B\) through the loop as a function of time \(t\). Which of the following statements correctly relates the features of the graph to the electrical or mechanical behavior of the loop?
