How it works

What this project is testing.

Induction heating uses a changing magnetic field to heat metal without touching it. The field drives swirling currents inside the metal, and the metal warms because those currents meet resistance.

The experiment demonstrates electromagnetic induction in a very tangible way: electricity in a coil becomes magnetism, magnetism becomes current inside the workpiece, and that current becomes heat.

E = - \frac{d Φ _{B}}{d t}

A changing magnetic flux induces voltage around a conducting path.

P = I^{2} R

The induced currents heat the metal through ordinary resistive heating.
