Abstract
An instrumentation apparatus with curable internal magnets is shown. The apparatus comprises a magnetic rotor and a rotatably mountable spindle to which the magnetic rotor is attached. A support structure to which the spindle is rotatably mounted defines at least one retaining area. A material is poured into and cured in the retaining area, and then charged to form a magnet. The molded and cured magnet provides a constant magnetic field that acts upon the magnetic rotor, providing a return-to-zero function or a volt gauge function for the instrumentation apparatus.
