Abstract
A write head magnetizes magnetic-ink characters for a MICR system. A magnetic assembly defines a first pole in a first location and an opposite pole in a second location. A first pole piece and a second pole piece, spaced by a gap therebetween, are provided, the first pole piece disposed adjacent the first location and adapted to conduct a magnetic field from the first pole to the gap. A selectably positionable member is disposed between the second location and the second pole piece, the positionable member being adapted to affect a magnetic field from the second location through the second pole piece to the gap, thereby facilitating selectable alteration of a magnetic field profile across the gap.
