The magnetic field B through the rectangle of Fig. 32-6 is shown at a different instant in part 1 of the figure here, B is directed in the xz plane, parallel to the z axis, and its magnitude is increasing. (a) Complete part 1 by drawing the induced electric fields, indicating both directions and relative magnitudes (as in Fig. 32-6). (b) For the same instant, complete part 2 of the figure by drawing the e lectric field of the electromagnetic wave. Also draw the induced magnetic fields, indicating both directions and relative magnitudes (as in Fig. 32-7).

Explanation

(a) Use Eq. 32 -5 . On the right side of rectangle `vecE` is in the negative y direction on the left side `vecE+dvecE` is greater and in the same direction (b) `vecE` is downward . On the right side `vecB` is in negative z -direction on the left side `vecB+dvecB` is greater and in the same direction .
