ABSTRACT:
The specification describes a low reluctance magnetic circuit for a dot matrix line printer for retaining hammersprings by the magnetic circuit having pairs of pole pieces formed of magnetically conductive sheets having a space for receipt of a permanent magnet. A coil is wrapped around a portion of each of the pole pieces between the magnet and the ends to provide a reverse magnetic field to the magnetic field provided by the permanent magnet. A magnetic shunt is established between the pole pieces to provide a greater magnetic effect. The pole pieces are sized and plated at the ends, with a spaced wear bar between them to provide improved performance and longer wear.
