## Calculator of induction heating power

This section is an interactive calculator. |

The order of magnitude for the required induction heating power can be estimated as a rough approximation, through a number of simplifying assumptions:

- only the heated layer is taken into account (the rest of the material is ignored)
- the same heating power is delivered to the material during the whole heating time (it is controlled regardless of temperature of the material)
- magnetic permeability is assumed constant
- transition to paramagnetism is not taken into account
- skin depth is calculated for resistivity at the hottest temperature
- the suggested frequency is estimated by assuming the skin depth being 4 times thinner than the heated layer
- apart from resistivity all other values are assumed constant, and melting or any phase transition is ignored.

- Material data such as resistivity, heat capacity, and permeability was taken from several sources, but mainly from Engineering Toolbox {accessed 2023-08-13}.
- This calculator was inspired by Plustherm, Online induction heating power calculation {accessed 2023-08-12}.
