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. Electromagnetic door holder - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_door_holder

   Wall-mounted electromagnetic door holder securing a door in the open position. An electromagnetic door holder (electromagnetic door holder and release or hold-open device, sometimes informally called a mag hold open or electric doorstop) is a simple electromechanical mechanism which can be used to hold a fire door or security door open until given a signal to release.

4. 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]

5. Electromagnetic lock - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_lock

   Quick to operate: Magnetic locks unlock instantly when the power is cut, allowing for quick release in comparison to other locks; Sturdy: Magnetic locks may also suffer less damage from multiple blows than do conventional locks. If a magnetic lock is forced open with a crowbar, it will often do little or no damage to the door or lock.

6. Chuck (engineering) - Wikipedia

   en.wikipedia.org/wiki/Chuck_(engineering)

   A drill chuck is a specialised self-centering, three-jaw chuck, usually with capacity of 0.5 in (13 mm) or less, and rarely greater than 1 in (25 mm), used to hold drill bits or other rotary tools. This type of chuck is used on tools ranging from professional equipment to inexpensive hand and power drills for domestic use.

7. Quick coupler - Wikipedia

   en.wikipedia.org/wiki/Quick_coupler

   Quick couplers (also called quick hitches) are used with construction machines to allow the rapid change of working tools or buckets and attachments on the machine. They remove the need to use hammers to manually drive out and insert the mounting pins for attachments.

8. Car lift - Wikipedia

   en.wikipedia.org/wiki/Car_lift

   Car lift may refer to: Car elevator, a device which transports cars between different floors of a building. Car lift, car hydraulic lift, 2 post lift or 2 column lift, a device which mechanically lifts a car up, so that the mechanic can work underneath. Car ramp, a device which raises a car from the ground for access to its undercarriage.

9. 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 ...
