2. Magnetic switchable device - Wikipedia

   en.wikipedia.org/wiki/Magnetic_switchable_device

   A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...

3. Magnetic pulse welding - Wikipedia

   en.wikipedia.org/wiki/Magnetic_pulse_welding

   Magnetic pulse welding (MPW) is a solid state welding process that uses magnetic forces to weld two workpieces together. The welding mechanism is most similar to that of explosion welding. [1] Magnetic pulse welding started [clarification needed] in the early 1970s, when the automotive industry began to use solid state welding. [citation needed]

5. Clamp holder - Wikipedia

   en.wikipedia.org/wiki/Clamp_holder

   A clamp holder or clamp fastener is a piece of laboratory apparatus that is used to secure laboratory clamps, such as extension-type utility clamps, or other attachments to a retort stand or lab frame. [1] The material can be made up of brass, cast iron, stainless steel, aluminium or nickel-plated zinc. [2]

6. Electropermanent magnet - Wikipedia

   en.wikipedia.org/wiki/Electropermanent_magnet

   The magnetic field generated by the EPM is produced by the permanent magnets not by electric currents and this is the main difference with the electromagnets. An EPM uses only a pulse of current to magnetize one of the magnet in a desired direction (turning on and off the external magnetic field of the latch).

7. Arc blow - Wikipedia

   en.wikipedia.org/wiki/Arc_blow

   Magnetic arc blow is known to begin at field densities as low as 10 gauss and becomes severe at densities of, equal to or greater than, 40 gauss; it is directional and can be classified as forward or backward moving along the joint, but can occasionally occur to the sides depending on the orientation of the poles to the workpiece.
