Chapter 9, Problem 9.19P

In Section 9.1. Faraday’s law was used to show that the field E = -1_2kB0ekt pa∅ results from the changing magnetic field B = B0 ektaz. (a) Show that these fields do not satisfy Maxwell’s other curl equation. (b) If we let B0 = 1 T and k = 106 s-1 , we are establishing a fairly large magnetic flux density in 1 fis. Use the V x H equation to show that the rate at which Bz should (but does not) change with p is only about 5 Ă— 10 T per meter in free space at t = 0.
