  • heating material or “heater material” refers to material that is heatable by penetration with a varying magnetic field.

  • Induction heating is a process in which an electrically-conductive object is heated by penetrating the object with a varying magnetic field.
  • An induction heater may comprise an electromagnet and a device for passing a varying electrical current, such as an alternating current, through the electromagnet.
  • a varying electrical current such as an alternating current
  • the electromagnet and the object to be heated are suitably relatively positioned so that the resultant varying magnetic field produced by the electromagnet penetrates the object, one or more eddy currents are generated inside the object.
  • the object has a resistance to the flow of electrical currents. Therefore, when such eddy currents are generated in the object, their flow against the electrical resistance of the object causes the object to be heated. This process is called Joule, ohmic, or resistive heating.
  • An object that is capable of being inductively heated is known as a susceptor.
  • Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by penetrating the object with a varying magnetic field.
  • a magnetic material can be considered to comprise many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such material, the magnetic dipoles align with the magnetic field. Therefore, when a varying magnetic field, such as an alternating magnetic field, for example as produced by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes with the varying applied magnetic field. Such magnetic dipole reorientation causes heat to be generated in the magnetic material.
