  • Publication number: 20220249858
    Abstract: A magnetic stimulator includes a magnetic core, conductors, and a casing. The magnetic core includes a body portion, and leg parts that protrude in the same direction from the body portion. The conductors are wound in a coil manner respectively around the leg parts. The casing is a container for housing the magnetic core and the conductors. The leg parts of the magnetic core are formed such that cross-sectional areas thereof that are parallel to a plane which simultaneously crosses the leg parts gradually decrease from base parts on the body portion side toward tips.
