Chapter 25, Problem 4P

25.1 and 25.2 Polarization of waves and Discovery of electromagnetic waves

* (a) A uniform $\stackrel{\to }{B}$ field whose lines are oriented in the S-N direction increases steadily. Draw the $\stackrel{\to }{E}$ field lines of the induced electric field. (b) A uniform magnetic field whose lines are oriented E-W decreases steadily. Draw the $\stackrel{\to }{E}$ field lines of the induced electric field. (c) Repeat part (b) for a case when the $\stackrel{\to }{B}$ field changes at twice the rate.
