Radiate & Induction Heating

[polystriker]

Hi there!
I wonder what is definition of Radiate and Induction Heating?
What is the difference between these two heating?

Urgent!

Thanks a lot!

Radiant heating is subjecting an object to a source of heat such that the heat radiates from the source and heats the object. For example, a person standing in front of a fire is warmed by radiant heat from the flames.

Induction heating is heating an object (often a bearing or metallic ring) by passing an electrical current through it. An induction heater is basically just a transformer. The bearing is located such that it is a shorted turn of the transformer secondary. When the primary winding of the transformer is energised, current flows around the bearing, causing it to become hot.

Suggestion: The "Radiate" is appropriately or correctly applied to radiated heat (electromagnetic waves of certain frequency range) from some source, e.g. heat element.
The "Induction" heat is based on heat generation due to Eddy (or Foucault, Jean Bernard Léon, Pronounced As: zhäN bernär laôN fooko , 1819-68, French Physicist) currents caused by higher frequencies.
