Process
Induction heating is a non-contact process which uses the principle of electromagnetic induction to produce heat in a workpiece. By placing a conductive material into a strong alternating magnetic field, electrical current is made to flow in the material, thereby causing Joule heating. In magnetic materials, further heat is generated below the Curie point due to hysteresis losses. The generated current flows predominantly in the surface layer, the depth of this layer being dictated by the frequency of the alternating field and the permeability of the material.

Famous quotes containing the word process:
“My advice to people today is as follows: If you take the game of life seriously, if you take your nervous system seriously, if you take your sense organs seriously, if you take the energy process seriously, you must turn on, tune in, and drop out.”
—Timothy Leary (b. 1920)
“Rules and particular inferences alike are justified by being brought into agreement with each other. A rule is amended if it yields an inference we are unwilling to accept; an inference is rejected if it violates a rule we are unwilling to amend. The process of justification is the delicate one of making mutual adjustments between rules and accepted inferences; and in the agreement achieved lies the only justification needed for either.”
—Nelson Goodman (b. 1906)
“The American, if he has a spark of national feeling, will be humiliated by the very prospect of a foreigner’s visit to Congress—these, for the most part, illiterate hacks whose fancy vests are spotted with gravy, and whose speeches, hypocritical, unctuous, and slovenly, are spotted also with the gravy of political patronage, these persons are a reflection on the democratic process rather than of it; they expose it in its process rather than of it; they expose it in its underwear.”
—Mary McCarthy (1912–1989)
