Dear All Our group has been working on the design and fabrication of micro magnetic bearings. We have assembled the bearing and presently trying to quantify the force generated. It is designed to produce a force of around 50 mN. we greatly appreciate any ideas on how one can measure the force in this range. thanks in anticipation. Muralidhar Dr.Muralidhar K.
