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 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 radio station broadcasts at a frequency of 760 kHz. At a receiver some distance from the antenna, the maximum magnetic field of the electromagnetic wave detected is T.
What is the maximum electric field amplitude?
What is the wavelength of the electromagnetic wave?
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?
During a heartbeat, a heart produces a maximum potential of 4.00 mV across a 0.300-m distance. The changing potential generates a 1.00-Hz electromagnetic wave.
What is the maximum electric field strength produced during the heartbeat?
What is the maximum magnetic field strength produced during the heartbeat?
What is the wavelength of the electromagnetic wave produced by the heartbeat?
In a region of space, the electric field is pointed along the -axis, but its magnitude changes as described by
