  2. Track brake - Wikipedia

    en.wikipedia.org/wiki/Track_brake

    A magnetic track brake (Mg brake) is a brake for rail vehicles. It consists of brake magnets, pole shoes , a suspension, a power transmission and, in the case of mainline railroads , a track rod. When current flows through the magnet coil, the magnet is attracted to the rail, which presses the pole shoes against the rail, thereby decelerating ...

  3. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_brake

    Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...

  4. Magnetism - Wikipedia

    en.wikipedia.org/wiki/Magnetism

    Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.

  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. 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.

  7. Magnetic field - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field

    The magnetic field of larger magnets can be obtained by modeling them as a collection of a large number of small magnets called dipoles each having their own m. The magnetic field produced by the magnet then is the net magnetic field of these dipoles; any net force on the magnet is a result of adding up the forces on the individual dipoles.

  8. Inductrack - Wikipedia

    en.wikipedia.org/wiki/Inductrack

    Inductrack is a passive, fail-safe electrodynamic magnetic levitation system, using only unpowered loops of wire in the track and permanent magnets (arranged into Halbach arrays) on the vehicle to achieve magnetic levitation. The track can be in one of two configurations, a "ladder track" and a "laminated track". The ladder track is made of ...

  9. Transrapid - Wikipedia

    en.wikipedia.org/wiki/Transrapid

    The magnetic field generator, an important part of the engine being a part of the track, limits the system capacity. From a competition standpoint, the Transrapid is a proprietary solution. The track being a part of the engine, only the single-source Transrapid vehicles and infrastructure can be operated.
