Permanent magnets are made from special alloys (ferromagnetic materials) such as iron, nickel and cobalt, several alloys of rare-earth metals and minerals such as lodestone. Unlike electromagnets, permanent magnets produce a persistent magnetic field without the need for any external source of magnetism or electrical power. With over 20+ years of technical magnet expertise, AOMAG Magnetics specializes in the design, engineering and manufacturing of custom permanent magnets and precision magnetic assemblies for high-performance applications. AOMAG produce complex turnkey magnetic solutions for diverse markets across the globe. Focused Industries that we work with include military, aerospace, energy, semiconductor, R&D, automotive, industrial automation and more. permanent magnet is a kind of magnetic material that can produce a permanent magnetic field. In modern science and technology, permanent magnets are widely used in various fields, such as motors, generators, magnetic resonance imaging and so on. According to the material characteristics of permanent magnets, they can be divided into hard magnets and soft magnets. AOMAG is a high-tech enterprise specializing in the development, production and sales of permanent magnet materials.
Permanent magnets have a consistent non-varying magnetic field that has a north and south pole associated with them. The magnets come in different materials – rare earth, Alnico and hard ferrite. They all come in different sizes and shapes and have different magnetic strengths. The rare earth are the strongest, Alnico are the most stable, and ferrite are the least expensive. The magnetic strength is generally measured in gauss or milliTesla.
A Reed Switch requires either a permanent magnet or magnetic field in order to activate the switch, thus it is commonly called a magnetic reed switch. Magnets have reversible and irreversible demagnetization specifications. Engineers should consider shock, vibration, strong external magnetic fields as well as high temperatures in their designs. All these factors influence the magnetic force and the long term stability in different ways.
Preferably the magnet is mounted on the moving part of the application. Professional tuning of magnet and reed switch pairing can improve the functionality of the whole sensor-magnet system.We deliver more than 100 million permanent magnets to countries in America, Europe, Asia and Africa every year.
