A magnetic flux converging type high speed electromagnet comprising a magnetic frame and an exciting coil assembly positioned within the frame. The exciting coil assembly includes a plurality of series-connected exciting coil portions spaced from each other along a longitudinal axis and a plurality of conductor plates interposed between the coil portions. Each of the conductor plates is provided with a hollow cylindrical member having a slit extending in the longitudinal direction which is continuous with a radial slit in the conductor plate, and each of the hollow cylindrical members extends along the longitudinal axis from a corresponding conductor plate toward a first end of the magnetic frame. A first end conductor plate not having the hollow cylindrical member is interposed between the first end of the magnetic frame and an adjacent exciting coil portion of the exciting coil assembly. A second end conductor plate having a hollow cylindrical member is interposed between a second end of said magnetic frame and another adjacent exciting coil portion of the exciting coil assembly.
