Abstract
(EN)
There is obtained a superconductive magnet in which there are reduced the machining costs and the amount of materials for bobbins and supporting members that support coils. In a superconductive magnet provided with a first group of coils serving as main coils (2) for generating a magnetic field and a second group of coils serving as shield coils (3) that are arranged coaxially with the first group of coils and generate a magnetic field whose direction is opposite the direction of a magnetic field generated by the first group of coils so that a magnetic field that leaks outside is cancelled, the second group of coils are arranged at axis-direction positions where axis-direction electromagnetic force generated by the first group of coils and exerted on the second group of coils and axis-direction electromagnetic force generated by the second group of coils balance with each other and cancel out each other.
