2. Electromagnetic lock - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_lock

   The magnetic lock is suitable for both in-swinging and out-swinging doors. Brackets (L bracket, LZ bracket, U bracket) are used to orient the armature for use with both applications. Filler plates are also used to provide a large, flat mounting area on the door frame when the electromagnet is larger than the available mounting space on the door ...

3. Magnetic implant - Wikipedia

   en.wikipedia.org/wiki/Magnetic_implant

   For this reason, the most common magnet size is a 3×1mm neodymium disk magnet. Usually the magnets used are of the highest strength available, as a stronger magnet leads to higher magnetic field sensitivity. Perhaps the most important consideration is a coating for the magnet, as typical neodymium disk magnets are not suitable for implantation.

4. Pole piece - Wikipedia

   en.wikipedia.org/wiki/Pole_piece

   A magnet keeper is a specialised pole piece used to temporarily connect the poles of a permanent magnet, to help to preserve the magnetism, and for safety in the case of large and powerful magnets. Another specialised pole piece is the armature of an electromechanical solenoid , which produces work by being attracted by an electromagnet when ...

5. Refrigerator magnet - Wikipedia

   en.wikipedia.org/wiki/Refrigerator_magnet

   A collection of refrigerator magnets A refrigerator magnet displaying a sexual assault hotline's telephone number. A refrigerator magnet or fridge magnet is a small magnet, often attached to an artistic or whimsical ornament, which may be used to post items such as shopping lists, Christmas cards, child art or reminders on a refrigerator door, or which simply serves as decoration.

6. Magnet - Wikipedia

   en.wikipedia.org/wiki/Magnet

   A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

7. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   Due to ceramic ferrite magnet’s weaker magnetic fields compared to superconducting magnets, they are sometimes used in low-field or open MRI systems. [41] [42] These magnets are favored in certain cases due to their lower cost, stable magnetic field, and ability to function without the need for complex cooling systems. [43]

8. Neodymium magnet - Wikipedia

   en.wikipedia.org/wiki/Neodymium_magnet

   The greater forces exerted by rare-earth magnets create hazards that may not occur with other types of magnet. Neodymium magnets larger than a few cubic centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a ferrous metal surface, even causing broken bones. [46]

9. Quadrupole magnet - Wikipedia

   en.wikipedia.org/wiki/Quadrupole_magnet

   Quadrupole magnets are useful as they create a magnetic field whose magnitude grows rapidly with the radial distance from its longitudinal axis. This is used in particle beam focusing. The simplest magnetic quadrupole is two identical bar magnets parallel to each other such that the north pole of one is next to the south of the other and vice ...
