Consider the electric field pattern of a sinusoidally oscillating dipole in Figure 30.14.

(a) At \(t=\frac{3}{4} T\), where along the horizontal axis bisecting the straight line connecting the two poles is the electric field increasing with time? Where is it decreasing?

(b) Based on your answer to part \(a\), what pattern of magnetic field lines do you expect in the horizontal plane that bisects the straight line connecting the two poles?
