"Terman`s comment on page 2 of the 1955 edition simply points out the
operation of Faraday`s Law."

Faraday`s law says that, while the magnetic flux linked with a closed
path loop or coil is changing, the closed path is the source of an
electromotive force (voltage) whose magnitude depends only upon the rate
of change of the flux through the path.

If we cause an antenna to be surrounded by an altrernating magnetic
field, a voltage will be induced in the antenna in accordance with
Faraday`s law, This induced voltage is necessary and sufficient to
account for all of the energy received by the antenna.
