Consider a single-loop coil whose magnetic flux is given by Figure 23-32.
(a) Is the magnitude of the induced emf in this coil greater near t = 0.4 s or near t = 0.5 s? Explain.
(b) At what times in this plot do you expect the induced emf in the coil to have a maximum magnitude? Explain.
(c) Estimate the induced emf in the coil at times near t = 0.3 s, t = 0.4 s, and t = 0.5 s.
