Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]
A Magna Doodle drawing board. Magna Doodle is a magnetic drawing toy, consisting of a drawing board, a magnetic stylus, and a few magnet shapes.Invented in 1974 by Pilot Corporation, [1] over forty million units have been sold to date worldwide, under several brands, product names and variations, including Tyco and Mattel/Fisher Price.
The Levitron top device is a design that served as a base for the manufacture of a series of commercial toys under this brand that employ the phenomenon known as spin-stabilized magnetic levitation. This design, with moving permanent magnets, is quite distinct from other versions which use changing electromagnetic fields, levitating various ...
A "horseshoe magnet" made of Alnico 5, about 1 inch high.The metal bar (bottom) is a keeper. A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have low magnetic ...
A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...
Correlated magnets can be programmed to interact only with other magnetic structures that have been coded to respond. Correlated magnets can even be programmed to attract and repel at the same time. Compared to conventional magnets, the correlated magnet provides much stronger holding force to the target and stronger shear resistance.
