The principle of electromagnetic induction is the principle of electromagnetic induction, that is, the principle that the heated object is placed in the magnetic field for its own heating due to the magnetic energy of the induction. That is to say, heating an object with an electromagnetic heater is actually the effect of converting the electric energy into magnetic energy to heat the heated object itself.

We often use this picture to demonstrate the working principle of the electromagnetic heater. The heated object wrapped by the red electromagnetic wire is placed in the strong magnetic field produced by the electromagnetic heater, and it generates itself through the induction of magnetic energy. The following picture is taken as an example of the heating plastic machinery. The heating process is introduced in detail, and the reaction is also the working principle of the electromagnetic heating.

The practical application of the electromagnetic heating principle is the three step: the electromagnetic heating cable sends out the high frequency magnetic field, the high frequency magnetic force line makes the material barrel self heating, and finally the plastic is heated and melted.
The main task of electromagnetic heating controller is 220V/380V, conversion of 50/60Hz AC to DC 20-40KHz, and then converted to DC output high speed high frequency high voltage current, high voltage current flowing through the formation of high temperature high pressure electromagnetic cable made of alternating magnetic field and the metal cylinder containing the magnetic contact high speed magnetic line cutting, vortex formation, the self heating material tube.
Every time I explain the working principle of the electromagnetic heater in detail, then I know what the function of the electromagnetic heater is and how good it will do for us.
In the understanding of the working principle of the electromagnetic heater at the same time, you are not even clear form of electromagnetic heater as well as parts of the role, in the familiar with and know the different components of the role, we do in the installation, maintenance, maintenance of the effect will be different, will help us better use the maximum degree is low, play the heating effect of electromagnetic heater.
