What is the magic of suspension generated by electromagnetic induction heating equipment?

The principle of this magical induction heating is the dual phenomenon of electromagnetic induction heating equipment and electromagnetic suspension. The heating of the electromagnetic sensing equipment is placed in a rapidly changing magnetic field with electromagnetic induction, thereby generating vortex in the metal. The current flows over the resistance of the metal itself and heated, and finally melt the metal.

Why is copper or aluminum used for electromagnetic suspension? This experiment cannot be performed due to iron or steel's self -ironing interference. Aluminum and copper are the most suitable materials. Please note that the magnetic suspension itself does not require superconductors, although superconducting materials saves a lot of electricity.

In the field of industrial manufacturing, there is also such a technology called suspended melting, and metal materials have suspended sensor melting technology under the action of external magnetic fields. This smelting method was developed in 1923. The principle is that when the induction coil of the inductive heating equipment passes the high -frequency current, the high -frequency magnetic field is generated, so that the metal sample (conductor) in the coil has magnetic field. The magnetic field generated by the coil is the opposite, which generates exclusion force to suspend the conductor in the space. There is no pollution caused by the suspended melting.

Mainly used for small -scale pure metal smelting research and metallurgical balance research. This smelting method has problems such as too small furnace capacity (Urke) and difficulty in temperature control. The suspended smelting process is a very beautiful technology!
