An isotropic point source emits light at wavelength 470 nm, at therate of 170 W. A light detector is positioned 390 m from thesource. What is the maximum rate dB/dt at which the magneticcomponent of the light changes with time at the detector'slocation? The speed of light is c = 3 × 108 m/s, and µ0 = 4p × 10-7H/m.
