What is a superconducting magnet?
Superfective magnet is an electromagnet where the coils are made of type II superconductor. It can easily create a stable magnetic fields of 100,000 Ourstered (8,000,000 amps per meter). They produce stronger magnetic fields than standard iron electromagnets and less operation costs. When some metals and ceramics are cooled from a series of degrees near absolute zero, they lose electrical resistance. This temperature is called critical temperature (TC) and is different for each material. If there is no electrical resistance, the electrons may roam freely throughout the material. The element can hold a large amount of current for a long time without losing energy like warmth. This ability to maintain an extreme electric charge is called superconductivity.
Most metals have a woven atomic structure. Their electrons are freely held so that they can easily move in and out of the woven pattern. As the electrons move, it collides with atoms and loses energy in the form of heat. Metals are able to warm up and control electricity very well. ItThere is a reason why pots and pans and things like toast furnaces are constructed from metal.
In the superconductor, electrons travel in pairs and move between atoms instead of colliding with them. As a negatively charged electron movement, although binding with positive atoms, it pulls these positive atoms. Another electron is attracted to resistance and pairs with the original electron. They are constantly released and associated with other electrons, but with small to no resistance. For this reason, they do not lose heat and energy as standard metal.
type II superconductors are a type used in the coils of a superconducting magnet. Superconduc type Iitor reaches TC at a lower temperature than type I superconductors. They have a gradual transition from superconducting to their normal state in the magnetic field. These two properties allow them to perform higher currents than type I.
Superfective magnet can be used for magnetic levitation. In MeisThe driving effect is placed under the magnet and cooled by liquid nitrogen. The superconductor is open to accept the charge because it is cooled, the magnet induces the current and thus the magnetic field in the superconductor and the magnet begins to float above this field.
Research is in the works for the use of a superconducting magnet for a levitation train system. It is also considered to produce small but powerful magnets that are used to display magnetic resonance imaging (MRI). Long -term plans include discovering materials that can produce superconductivity without freezing. If this material is discovered, it will change the future of many Fields Including Transport and Energy Production.
