Modulation of an induced magnetic field created by running an electron flow through a copper coil wrapped around a ferrite iron core. The frequency is determined by the number of windings. ie. Approximately 35000 hz with 500 turns of wire on a 10mm wide, 6 inch ferrite rod utilizing a Hartley oscillator for magnetic signal generation. The receiver uses a similar ferrite rod with a similar number of windings. No antenna needed since communication is via modulation of a magnetic field flux not via RF or radio frequency.

A TV remote control, which has to convey much more information, is usually an infrared device. This carries some modulation to change channels, alter volume, and to alter display characteristics of the display.
Modulation is a method of transferring informationon a carrier. In the TV case, usually a digital signal.
