A bar magnet is a rectangular object made of iron or steel that has a magnetic field. Each end is called a pole, one is north and the other is south. They are used to pick up small ferromagnetic objects and have been used for years to demonstrate magnetic fields. A bar magnet is a […]
“Super magnets” are neodymium magnets or powerful electromagnets used in fMRI imaging. They are much stronger than ferrite magnets and can be hazardous to pacemaker wearers. Neodymium magnets are made of an alloy of neodymium, iron, and boron and can hold 1300 times their own weight. They have various uses but must be used with […]
Permanent magnets are always magnetic, unlike electromagnets which require an electric current. They are made of substances like magnetite or neodymium and have two poles, north and south. They have many uses, from refrigerator magnets to electric motors, but can also be a nuisance, erasing data from ATM cards and hard drives. A permanent magnet […]
Flexible magnets can be cut into various shapes and used in factories, schools, homes, and businesses. They are made by extrusion or calendering and can be die-cut or customized. They are often used for advertisements, safety notices, and toolbox labels. A flex magnet is a type of magnet that is bendable and can be cut […]
A permanent magnet synchronous generator (PMSG) uses magnets instead of coils to produce magnetic fields, reducing power and allowing for operation at different speeds. PMSGs are used in wind generators, hybrid cars, and electric cogeneration. Rare earth magnets are used in PMSGs for their durability. A permanent magnet synchronous generator (PMSG) is an electrical generator […]
Conveyor magnets trap magnetic materials on a production line and can target ferrous and non-ferrous metals. They can be used for quality control, material separation, and protecting machinery. They come in different forms and can be customized for specialized applications. Safety precautions should be taken around strong magnets. A conveyor magnet traps magnetic material as […]
Ferrite magnets are ceramics that attract ferromagnetic materials and other magnets. They are the simplest and cheapest type of magnet, with two categories: soft and hard. Their strength is measured in tesla, with the strongest being 45 tesla in a laboratory. Ferrite magnets are a large class of magnets that include chemical compounds such as […]
Superconducting magnets use type II superconductors to create stronger magnetic fields than standard electromagnets. They operate at low temperatures, allowing electrons to move freely without resistance, and are being researched for use in levitating rail systems and MRI machines. A superconducting magnet is an electromagnet in which the coils are made of a type II […]
A horseshoe magnet is a U-shaped metal object that produces a magnetic field and remains magnetized. It was made as an alternative to the weaker bar magnet and is still effective for classroom demonstrations and collecting small metal objects. The magnetism is produced by the movement of electrons in atoms with unpaired electrons, such as […]
Neo magnets are made of an alloy of neodymium, iron, and boron, and are the strongest permanent magnets known. They are used in various applications, but caution must be taken as they are highly brittle and can lose magnetism when exposed to high temperatures. Safety precautions must be observed as they can damage electronic devices […]
Neodymium is a powerful and affordable rare earth magnet used in various industries and hobbies. It contains two neodymium atoms, 14 iron atoms, and one boron atom. Its strength is measured in gauss ratings and can value up to 13,500 gauss. It is used in computer hard drives and high-end lecturers. However, it loses strength […]
Magnets can be permanent or electromagnets and non-magnets can be ferromagnetic, paramagnetic, or diamagnetic. Magnet strength is measured in gauss and can be affected by various conditions. Rare earth magnets are measured in pull force. Magnet strength decreases as you move away from the surface. A magnet is any object that produces its own magnetic […]
Magnet schools were created to attract gifted students and meet federal desegregation bills. Parents should consider whether their child would benefit from an accelerated pace and advanced techniques. Magnet schools generally have higher education levels and funding, but there may be logistical and financial considerations. Decisions regarding a child’s education are always serious and parents […]
The lodestone resonator is a fictional device in Philip Pullman’s His Dark Materials series that allows communication between different universes. It is used by Gallivespians in their war against the Authority and works through quantum entanglement, although it is not scientifically feasible in our world. A lodestone resonator is one of several fictional devices appearing […]
A Magnet hospital is a healthcare facility with exceptional nursing standards and a good working environment for nurses. They must meet specific standards in five areas and pass a site visit to receive the designation for four years. There are criticisms of the Magnet Recognition Program, but Magnet facilities tend to rank high in national […]
