Definition

Noun: A method of heating an electrically conductive material (usually a metal) by generating heat within the material itself. This is achieved by using electromagnetic induction to create eddy currents inside the object. The material is placed within a varying magnetic field produced by an alternating current passing through a coil. The resulting eddy currents flow through the material's resistance, generating heat directly inside the object.

Usage

"Induction heating" is a technical term used in industrial, manufacturing, and scientific contexts. It describes the process itself, not the device (which is an induction heater or induction furnace).

Examples

• Noun:
  • Induction heating is commonly used for metal hardening and brazing.
  • The efficiency of the induction heating process is very high.
  • They melted the sample using a method called induction heating.

Advanced Usage

• "to subject to induction heating": To apply the induction heating process to an object.
  • The steel rod was subjected to induction heating before it was forged.

Variants and Related Words

• Induction heater (n): The device or equipment used to perform induction heating.
• Induction furnace (n): A type of induction heater used for melting metals.
• Electromagnetic induction (n): The fundamental physical principle that makes induction heating possible.

Synonyms

• Eddy-current heating: A more specific technical synonym, as eddy currents are the direct cause of the heating in this process.

Related Phrases

• Induction coil: The coil of wire that carries the alternating current and generates the necessary alternating magnetic field for induction heating.
• Skin effect: A related phenomenon in induction heating where the electric current concentrates near the surface of the conductor, affecting the heating depth.

Noun

1. the heating of a conducting material caused by an electric current induced in it
