Question
The magnetic flux through three different coils is changing as shown in Figure $P 18.17$ . For each situation, draw a corresponding graph showing qualitatively how the induced emf changes with time
Step 1
For the first graph, the flux decreases linearly with time, so we can write $\Phi=-\Phi_{0}+c t,$ where $c$ is a positive constant. For the second graph, the flux decreases quadratically with time, so we can write $\Phi=\Phi_{0}-c t^{2}$. Show more…
