    摘要: An electromagnet device which generates magnetic field in the direction perpendicular to the inserting direction of an inspection subject is reduced in size and weight by removing unnecessary arrangement as much as possible. A magnetic resonance imaging device is also provided. The electromagnet device comprises a first coil (31) through which a first circular current (J1) circulates forward, a second coil (32) through which a second circular current (J2) circulates reversely, and a coil group (30) through which a plurality of circular currents (J3-J6) circulate alternately forward and reversely. The first coil (30), the second coil (32) and the coil group (30) are arranged in this order to increase the angle of elevation θ (θ1
