HOW TO MAKE INDUCTION HEATING, CONTACTLESS HEATING WITH MAGNETIC FIELD
Electromagnetic induction heating works and even very well. In industry, and particularly in that of delicate brazing and sensitive welding, induction heating is very widespread.
An electromagnetic induction heater has appeared on the market, but it is still an improved electric heater. There are also materials that pompously claim to operate by induction but thermally.
Expensive in terms of electricity and various materials, induction heating does not meet current energy saving standards.
The principle of induction heating
Generation of an electromagnetic field
In induction heating, the generation of an electromagnetic field creates a release of heat. Moreover, hobs operating by induction are used daily by many households. Induction (electromagnetic) is therefore undoubtedly a principle of heat creation applicable in our homes.
Induction heating is a contactless method of heating metals (steel, copper, aluminum, brass) and semiconductors (carbon, graphite, silicon carbide). If the object to be heated does not need to conduct electric current, it must be permeable to an external magnetic field (eddy current). When this object is placed in the heart of an intense magnetic field, the molecules of this object are excited, collide with each other (hysteresis) which produces heat that this object then diffuses.
An electric current sent through an inductor
Induction heating requires an electric current which will be raised in frequency by a generator before being sent to an inductor. The inductor is generally a copper winding whose length and diameter are proportional to the part to be heated.
If the industrial applications are numerous, with regard to the expenditure in electric current, in equipment (generator) and in copper for the inductor, it is immediately conceivable that the principle of heating by electromagnetic induction is difficult to apply to domestic heating.
Advantages and disadvantages of induction heating
A short time ago appeared on the market a single radiator applying the principle of electromagnetic induction, but it is in fact a relatively classic electric radiator which has the particularity of releasing a sufficient magnetic field to recharge a battery (smartphone , tablet) by induction.
Beautiful and elegant, this device is still only an electric radiator whose particularity is to recharge mobile devices placed on its surface thanks to "calopiles", which is now the task of many wireless chargers sold from from €10.
