Induction Heating Simulation

Explore how cooking evolved from open flames to modern induction cooktops that heat only the pan, not the surface. See how electromagnetic and thermal simulations help optimize power transfer, temperature distribution, and EMF levels for safer, more efficient cooking.

Induction heating uses high-frequency magnetic fields to heat metal directly. EMWORKS EMAG predicts coil inductance, magnetic flux density, and heating behavior for induction cooktops and power applications.

This example uses EMWORKS Transient Magnetic study coupled with thermal analysis to simulate induction heating of a spherical workpiece inside a multi-turn coil. The solver computes magnetic flux density, eddy current distribution, and temperature evolution so you can study heating rates, penetration depth, and hardening profiles without physical trials.

This example uses EMWORKS EMAG to simulate induction heating of a graphite crucible driven by a multi-turn copper coil. An AC Magnetic study coupled with transient thermal analysis captures frequency-dependent fields, eddy losses, and temperature evolution using temperature-dependent graphite properties.

A magnetizer (magnetic flux concentrator) focuses magnetic flux into a target region of a workpiece. Using EMWorks, you can model ferrite magnetizers to boost induction heating efficiency and confine temperature to critical areas.

High-frequency proximity heating uses induced currents on facing mold plates to achieve fast, selective surface heating in injection molding. EMWorks couples AC magnetic and transient thermal analysis to predict current density, temperature distribution, and coil settings for precise mold temperature control and shorter cycle times.

This application note studies induction brazing of a cylindrical copper workpiece using 3D coupled electromagnetic–thermal finite element analysis. A 13-turn copper coil operating at 75 kHz with a peak current of 300 A is modeled to quantify magnetic field distribution, eddy current density, ohmic losses and resulting temperature rise in the workpiece. The results show surface-concentrated currents due to the skin effect, non-uniform temperature between 26°C and 28.24°C after 1 s, and clear links between field distribution, power loss and thermal response, providing a basis for refining induction coil and process parameters.
