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 temporary way.
The powder-in-tube (PIT, or oxide powder in tube, OPIT) process is an extrusion process often used for making electrical conductors from brittle superconducting materials such as niobium–tin [10] or magnesium diboride, [11] and ceramic cuprate superconductors such as BSCCO. [12] [13] It has been used to form wires of the iron pnictides. [14]
A pinched aluminium can, produced from a pulsed magnetic field created by rapidly discharging 2 kilojoules from a high-voltage capacitor bank into a 3-turn coil of heavy gauge wire. Electromagnetic forming ( EM forming or magneforming ) is a type of high-velocity, cold forming process for electrically conductive metals, most commonly copper and ...
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating
The reaction plate consists of a 3.2 mm (0.125 inch) thick aluminum or copper plate bonded to a 6.4 mm (0.25 inch) thick cold rolled steel sheet. [11] There is an air gap between these two parts that creates the frictionless property an electromagnetic propulsion system encompasses.
Avoid storing your credit card near magnets or other magnetic items. If your purse or wallet has a magnet on it, ensure the magnetic strip on your card faces away from the magnet to help avoid damage.
Most metals, including gold, silver and aluminum, are nonmagnetic. A large diversity of mechanical means are used to separate magnetic materials. [2] During magnetic separation, magnets are situated inside two separator drums which bear liquids. Due to the magnets, magnetic particles are being drifted by the movement of the drums.
For the small size applications, correlated magnets can be used in positioning devices, consumer electronics, magnetic couplings, and vehicle attachment. [4] Potential applications include attach and release work-holding mechanisms, magnetic separators, fluid seals and valves, motor and motion control, factory automation, prosthetics, security devices, and power generation.
