Basics of Induction Technology:

10 Key Questions from the Industry Answered

What is induction technology?

Induction technology is based on the principle of electromagnetic induction, where an electrical voltage is induced in a neighboring conductor (workpiece) by a changing magnetic field.

Image source: J. Fasholz et al.: Inductive Heating. Process Information, Essen: RWE Energy, 1991.
For what is induction technology used in the industry?

In industry, induction technology is primarily used to heat metallic materials for processes such as hardening, melting, welding, joining, and loosening, as well as for soldering, heating, and annealing.

What are the advantages of induction heating over other heating methods?

Induction heating is often faster, more precise, more efficient, and provides better control over the heating process. The energy input is consistent and reproducible. There are also no direct flames, which is often safer.

What role does frequency play in induction heating?

Frequency is crucial for the penetration depth of the magnetic field into the material. Higher frequencies produce a shallower penetration depth (also called the skin effect), which is suitable for thin workpieces, while lower frequencies penetrate deeper, suitable for thicker materials.

Image source: J. Fasholz et al.: Inductive Heating. Process Information, Essen: RWE Energy, 1991.
How does the material affect the effectiveness of inductive heating?

The effectiveness of inductive heating strongly depends on the electrical and magnetic properties of the material. Materials with higher electrical conductivity and permeability, like many metals, heat up faster. Non-conductive materials, such as most plastics, are less suitable for induction heating unless they contain conductive fillers.

How safe is induction technology?

When properly used, induction technology is safe. However, due to the high temperatures and strong magnetic fields involved, safety precautions and training are required.

Which materials can be treated with induction technology?

Many metals, especially conductive materials such as steel, copper, and aluminum, as well as silver, gold, and brass, can be thermally treated using induction technology. However, efficiency can vary depending on the material.

How efficient is induction heating compared to conventional methods?

Induction heating is often more energy-efficient than traditional methods because it directly heats the workpiece and not the environment, minimizing energy losses, leading to a reduction in CO2 emissions and other environmental impacts, especially when powered by renewable sources.

How does induction technology affect productivity in the industry?

Induction technology allows for faster and more precise heating of materials, leading to shorter process times and reduced energy consumption. Targeted and even heating can maintain higher quality standards and reduce scrap, thereby increasing overall productivity.

What are the limitations of induction technology?

Limitations include the need for a conductive material, the limited penetration depth of the magnetic field, and the requirement for specialized equipment and training.


In the multifaceted world of industrial technology, induction technology has taken a special place. The basic principle relies on generating an electrical voltage in a neighboring conductor (workpiece) through a changing magnetic field. This technique is primarily used in the industry for heating materials for various processes, including hardening, melting, welding, joining, soldering, heating, and annealing. A significant difference from conventional heating methods is the type of energy transfer. In induction heating, the transfer is done directly to the material through a changing magnetic field, while traditional methods often transfer heat through direct contact, radiation, or convection. In this type of heating, frequency plays a key role. Depending on whether a high or low frequency is chosen, the penetration depth of the magnetic field varies, directly affecting the heating efficiency of the target material. The efficiency of induction heating itself strongly depends on the electrical and magnetic properties of the material to be heated. Particularly conductive materials, like many metals, respond especially well to induction heating. In terms of productivity, induction technology proves superior, allowing for faster and more precise heating, leading to shorter process times and reduced energy consumption. From an environmental perspective, induction technology can contribute to reducing the CO2 footprint, especially when powered by renewable sources.
