- DIY simple high-frequency heating circuit to heat metal. Metals that are ferromagnetic are smeltable. For example: steel, cast iron, iron, steel, stainless steel..
- High-frequency heating electronic circuit, also known as induction furnace because the circuit generates high frequencies of thousands of Hz, the current flowing through the coil has a correspondingly high frequency and the magnetic field generated by the coil is also correspondingly high. . When the metal is put into the coil, the inside of the metal appears eddy currents or Faucault currents, because of the high frequency, the Faucault currents are very large, causing the metal to heat up very quickly.
- circuit using mosfet irf3205, resistor 330Ω, pulse diode fr203. - Visual representation of current and magnetic fields in coils. VIDEO : • How transformers work ...
