- Magnet - Wikipedia
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
- Magnetism - Wikipedia
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism
- Neodymium magnet - Wikipedia
Like other magnets, the neodymium magnet alloy is composed of microcrystalline grains which are aligned in a powerful magnetic field during manufacture so their magnetic axes all point in the same direction
- Magnet - Simple English Wikipedia, the free encyclopedia
When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction The force generated by the aligned atoms creates a magnetic field
- Magnet school - Wikipedia
Other magnet programs are within comprehensive schools, as is the case with several "schools within a school" In large urban areas, several magnet schools with different specializations may be combined into a single "center," such as Skyline High School in Dallas
- Electromagnet - Wikipedia
Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment
- Rare-earth magnet - Wikipedia
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets
- Magnet – Wikipédia
Magnet Železné piliny v magnetickom poli Magnet je objekt, ktorý v priestore vo svojom okolí vytvára magnetické pole Môže mať formu permanentného magnetu alebo elektromagnetu Permanentné magnety nepotrebujú k vytváraniu magnetického poľa žiadnu vonkajšiu energiu
