radiation and fields - W8JI.com

The radiation field allows us to communicate, not the electric or magnetic induction fields! Decay of the E-M radiation field is linear with distance, weakening in density only by increase of surface area of an imaginary sphere expanded out from the antenna. This means if we looked at the total energy in the imaginary sphere at any distance …

Induction heating - Wikipedia

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of an electromagnet, and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field …
