Neither an electrical field, nor a magnetic field will go anywhere by
themselves. Maxwell discovered that an electromagnetic wave exists when the
changing magnetic field causes a changing electric field (and vice versa)
and a wave cannot exist unless it is moving. Hertz proved the existence of
radio waves and the unit of frequency was named after him: I think is a
great tribute.
