Question

A localized source (such as an antenna, for example) is radiating electromagnetic waves outward in all directions. Far away from the source, at 8.5 km away, the intensity of the EM wave is measured to be 43 μW/m2. What is the peak value of the magnetic field of that EM wave at that location? (in T)

Answer 1

Answer: The magnetic field is 6.00 × 10^-10 T or 0.60 nT
