[MRI] (영/한) MRI Gantry - Resistive magnet, Permaenet magnet / 상전도자석, 영구자석
(English) Resistive magnet? 1. Iron-core resistive magnet type (H type) It is also called H type because it is made of an electromagnet by winding a coil of copper or aluminum around the center of iron. Relatively strong magnets can be made with little power, and unlike air-core resistive magnet type and superconducting magnet, magnetic flux is completely sealed. For this reason, devices for hum..
[MRI] (영/한) Gantry - Superconductive magnet (Quenching) / 갠트리 - 초전도 자석 (퀜칭)
(English) What is superconductivity? It refers to the state in which the electrical resistance becomes zero. Since there is no electric resistance, there is no electric loss due to heat generation, so a permanent magnetic field can be produced. However, this superconducting phenomenon occurs at an extremely low temperature close to the absolute temperature. Therefore, in order to cool the superc..
