Magnet Systems and Safety

Magnet Systems and Safety Permanent magnets and electromagnets are both switchable, but there is an important difference: permanent magnets are compact and always function – they retain their magnetic force; electromagnets switch quickly and without wear, and can also lift heavy loads, yet there is a risk of the load falling if the power is [...]

Magnet Materials

Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

  • Magnet Background of permanent magnets

Magnet Background

Magnet Background A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not [...]

Electromagnets Solenoids

Electromagnets & Solenoids Electromagnets are a non-permanent magnets that produced magnetic field. The magnetic field is created by a flow of an electric current through the coil. The magnetic field disappears when the current ceases (or in the case electromagnets of a permanent electromagnet, the magnetic field is present until a current is applied). As [...]

Causes and avoidance of rust spots on NdFeB magnets

Causes and avoidance of rust spots on NdFeB magnets After a period of time, the neodymium iron boron strong magnet will appear white or other color spots on the surface, and it will become rust spots when it develops slowly. Under normal circumstances, the plating of the electromagnet is not easy to appear rust spots, [...]

  • Door Holding Magnet

Door Holding Magnet

Door Holding Magnet Door holding magnets are used as locking devices for fire barriers to keep them in open state. Controlled by a smoke switch they release the door by disconnecting the power supply in case of fire hazard. Door holding magnets of the MPCO are primarily used as locking devices of fire barriers (fire [...]
