A graph of magnetic flux \Phi_B versus time t. The vertical axis is labeled \Phi_B and the horizontal axis is labeled t. Time markers t_1, t_2, and t_3 are spaced along the horizontal axis. From t=0 to t=t_1, the curve starts at the origin with zero slope and curves concave upward to a peak flux value \Phi_{max} at t=t_1. From t=t_1 to t=t_2, a straight line segment slopes steeply downward from \Phi_{max} to 0 at t=t_2. From t=t_2 to t=t_3, a straight horizontal line segment lies directly along the horizontal axis at \Phi_B = 0. No other labels, lines, text, or axes appear.
Magnetic flux vs. time through the wire loop.
A closed rigid wire loop of fixed resistance \(R\) is placed in a region of uniform magnetic field oriented perpendicular to the plane of the loop. The magnetic flux \(\Phi_B\) passing through the loop changes with time \(t\) as shown in the graph. Which graph best represents the induced current \(I\) in the loop as a function of time \(t\)?
