  2. Induction heating - Wikipedia

    en.wikipedia.org/wiki/Induction_heating

    Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...

  3. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    The magnetic field (B, green) is directed down through the plate. The Lorentz force of the magnetic field on the electrons in the metal induces a sideways current under the magnet. The magnetic field, acting on the sideways moving electrons, creates a Lorentz force opposite to the velocity of the sheet, which acts as a drag force on the sheet.

  4. Ferromagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferromagnetism

    One such typical material is a transition metal-metalloid alloy, made from about 80% transition metal (usually Fe, Co, or Ni) and a metalloid component (B, C, Si, P, or Al) that lowers the melting point. A relatively new class of exceptionally strong ferromagnetic materials are the rare-earth magnets.

  5. Electrodynamic suspension - Wikipedia

    en.wikipedia.org/wiki/Electrodynamic_suspension

    Electrodynamic suspension (EDS) is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. This induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart. These time varying magnetic fields can be caused by relative motion between two ...

  6. Electromagnetic propulsion - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_propulsion

    The reaction plate consists of a 3.2 mm (0.125 inch) thick aluminum or copper plate bonded to a 6.4 mm (0.25 inch) thick cold rolled steel sheet. [11] There is an air gap between these two parts that creates the frictionless property an electromagnetic propulsion system encompasses.

  7. Magnetic levitation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_levitation

    Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]

  9. Magnetic alloy - Wikipedia

    en.wikipedia.org/wiki/Magnetic_alloy

    A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve ): iron (Fe) , nickel (Ni) , or cobalt (Co) .
