Abstract
A static field magnet includes at least one loop coil pair including: a first loop coil to be supplied with an electric current in a first direction; and a second loop coil to be supplied with an electric current in a second direction, wherein: the first and second loop coils are arranged such that a first coil plane surrounded by a first loop forming the first loop coil and a second coil plane surrounded by a second loop forming the second loop coil are arranged along a specific direction in a specific plane without overlapping each other; the loop coil pair generates a static magnetic field parallel to the specific direction; and each of the first and second loop coils is formed such that a side along its major axis direction has a concave portion curved toward coil interior and toward its minor axis direction.
