Abstract
The electromagnetic force generator disclosed herein employs first and second elongate magnetic cores having transversely facing pole faces at each end, the cores being essentially parallel with pole faces aligned and facing. Between each pair of aligned pole faces is a relatively moveable core. A suspension provides a compliant mechanical connection between the moveable and elongate cores. The moveable cores are polarized by a permanent magnet mounted between the elongate cores and polarized along an axis paralleling the length of the elongate cores. Respective windings are provided around the elongate cores. A.c. energization of the windings creates a corresponding vibratory force between the movable cores and the elongate cores.
