An industrial induction heater uses electromagnetic energy to heat metals fast. This method is very efficient. Factories use this technology when they need quick and exact heating. When you put a metal part in the heater, a changing magnetic field goes through the metal. This follows Faraday’s Law of Induction. It makes electric currents flow inside the metal. These currents are called eddy currents. They make heat without touching the metal.
The global market size for industrial induction heaters will be USD 1.94 billion in 2024.
The expected growth rate is a CAGR of 4.9% from 2025 to 2034.

How Industrial Induction Heaters Work
Electromagnetic Induction Basics
Induction heating uses electromagnetic induction. You put a metal part inside a coil. The coil has an alternating current. This current makes a magnetic field that changes. The magnetic field goes through the metal part. Energy moves from the coil to the metal.
Here is how induction heating works step by step:
The coil gives energy to the metal part with electromagnetic fields.
The electric energy turns into heat inside the metal. This happens because of the Joule effect, which uses the formula P=I²R.
The heat spreads through the metal by thermal conduction.
The magnetic field gets weaker as you move away from the coil. If the magnetic field changes faster, it works better on the metal. Induction heating systems can heat metals quickly and efficiently. You can control the process very well. This is important for many jobs in factories.
Eddy Currents and Heat Generation
Induction heating makes a changing magnetic field inside the coil. This creates eddy currents in the metal. Eddy currents are loops of electric current inside the metal part. These currents move through the metal and meet resistance. The resistance turns electric energy into heat. The metal becomes hot, not the coil.
Induction heating systems use an electromagnet and an electronic oscillator. They make a high-frequency current. This current creates a magnetic field that moves very fast. The field goes deep into the metal and makes eddy currents flow. The heat comes from these currents fighting the metal’s resistance. This process is fast and does not need flames or touching the metal.
Induction heating is very efficient. It heats the metal at a molecular level. You can reach high temperatures in seconds. You can control the process very well. This helps you avoid overheating or damaging the metal.
Non-Contact Heating Process
Induction heating does not need to touch the metal part. The coil and the metal never meet. The energy moves through the air with the magnetic field. This non-contact process has many benefits.
Induction heating saves energy. It can turn up to 90% of the energy into heat. This helps you save money.
You can control how much heat you use. This lowers the risk of warping or damaging the part.
The process is very fast. You can heat parts to high temperatures in less than a second. This saves time and helps you work faster.
Non-contact heating is safer. You do not have to touch hot parts. There are no open flames or harmful gases.
Canroon’s induction heating technology gives even more benefits. Their products use rapid precision heating. They can reach over 1000°C in seconds. You get a safe and clean operation.
