ABSTRACT:
A weighing machine employing electromagnetic forces having a weighing pan which is mounted at the top portion thereof. An electromagnetic coil is employed in an air gap of a stationary permanent magnet system for generating a compensating force. The coil has a rectangular shape while the permanent magnet system consists of rectangular plates of magnetically active material with the vertical direction of magnetism being above or below the longer sides of the coil. A horizontal compensating force results.
