Using theorem and induction coil

Induction coil system is also called the closed electromagnetic inductioncollective hearing system, it is a collective of the earliest use of hearing aidtechnology. Now the induction coil system, hearing system is not only used forindustrial applications, more important is the distribution and industrial heating equipment is used, industrial power supply, an important part of industrialinduction heating power supply, domestic induction heating technologysubstantive progress from the beginning of 2003, according to differentworkpiece industrial heating, the induction coil is composed of an important part of the induction coil, general will go great current when working, the need to generate electromagnetic fields to the heating workpiece is large enough,so it itself may have a fever, in a studio need cooling water temperature drop,most of the film is: the application of industrial electric motor short circuit ringbrazing, evaporated aluminum coating, copper brazing, pipeline after preheating heat, and so some columns technology is development!

Principle of the induction coil:

The magnetic lines of force are in the same plane concentric circles and the vertical wires. The magnetic field lines from the center outward from dense to sparse, from strong to weak magnetic field. If the current through the wire is fixed, that is, direct current, then the generated magnetic field is also stable.When the current in a closed loop change inch, along with the currentchanges, the change in magnetic field generated by current. If the wirethrough the voice current generates a magnetic field, is also with the phoneticchange.
