ABSTRACT:
An electromagnetic assembly includes a core having an inner cylindrical portion and an outer cylindrical portion spaced from the inner cylindrical portion to provide space or a cavity for a bobbin. The bobbin is adapted to fit into the space provided in the core and has an elongated cylindrical body, a coil of wire wound around the body, and a flange at each end of the body for holding the coil on the body. A portion of one flange extends from the bobbin and overlaps a portion of the core. The bobbin is held in the core cavity by an interference fit provided between the overlapping, extended flange portion and the overlapped core portion.
