    Abstract: A hybrid-type magnet includes an electromagnet having a U-shaped core made of a magnetic material. The core includes a core body having outer ends and a pair of opposing arms extending upwardly from the outer ends of the core body, wherein each opposing arm includes an upper end having an end surface. An excitation coil is wound on the core. The hybrid-type magnet also includes a bar-like engagement member including a permanent magnet having a direction of magnetization, the permanent magnet being disposed between magnetic members. The magnetic members are closely joined to the respective end surfaces of the arms, the permanent magnet being positioned between the arms of the core, whereby the end surfaces of the opposing arms extend in a direction substantially parallel to the direction of magnetization of the permanent magnet.
