An electromagnetic wave from a wire antenna travels (from the
reader) toward the plane of the paper. At time t = 0.0 s it strikes
the paper at normal incidence. At point O and t = 0.0 s, the
magnetic field vector has its maximum value, 4.24×10-8
T, pointing in the negative y-direction. The frequency of this wave
is 1.28×106 Hz.
