In one embodiment, a static field magnet to be used for MRI 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 opposite to the first direction, wherein: the first and second loop coils are arranged such that a first coil plane and a second coil plane are along a primary direction without overlapping each other, the primary direction being included in a primary plane, the first coil plane being a planar area surrounded by a first loop that forms the first loop coil, the second coil plane being a planar area surrounded by a second loop that forms the second loop coil; and the loop coil pair is configured to generate a static magnetic field parallel to the primary direction.
