A radio transmitter broadcasts plane electromagnetic waves whose electric field amplitude at a particular location is V/m. What is the amplitude of the electromagnetic wave’s magnetic field at that location?
A plane electromagnetic wave travels northward. At one instant, its electric field has a magnitude of 6.0 V/m and points eastward. What is the magnitude of the magnetic field at this instant?
A certain 60.0-Hz ac power line radiates an electromagnetic wave having a maximum electric field strength of 13.0 kV/m.
What is the wavelength of this very-low-frequency electromagnetic wave?
What is the magnitude of the strongest magnetic field present in this wave?
