Suppose that charges on a dipole antenna oscillate slowly at a rate of 1 cycle/s, and the antenna radiates electromagnetic waves in a region of space.
a) If someone measured the time-varying magnetic field in the region and found its maximum to be 0.00150 T, what would be the maximum electric field, E, in the region, in units of volts per meter?
b) What is the period of the charge oscillation?
c) What is the magnitude of the Poynting vector?
