1. An ink jet print head for ejection of ink from an ink ejection nozzle comprising:

  • a substrate;

    a conductive coil formed on said substrate and operable in a controlled manner;

    a moveable magnetic actuator surrounding said conductive coil and forming an ink nozzle chamber between said substrate and said actuator, said moveable magnetic actuator further having said ink ejection nozzle defined therein;

    wherein variations in an energization level of said conductive coil cause said magnetic actuator to move from a first position to a second position, thereby causing a consequential ejection of ink from said nozzle chamber as a result of fluctuations in ink pressure within said nozzle chamber.
