ABSTRACT:
This invention provides an instrument responsive to acceleration forces. In the preferred embodiment, a body of magnetic material is positioned in a cavity such that it moves to a central position in response to a magnetic field and moves along a preselected path in response to acceleration forces. Means is included permitting the position of the body of magnetic material to be determined. The position of the body of magnetic material relative to the structure of the instrument is an indication of the magnitude of the acceleration force applied to the instrument.
