Abstract

The paper presents a new type of magnetic fluid acceleration sensor. The force between inertial magnet and repulsion magnet was computed by numerically calculation, and then the relationships between acceleration and displacement of inertial mass is obtained. The influence of distance of repulsion magnets, volume of magnetic fluid, magnetic induce of magnetic fluid and dimensions of magnetic core on output voltage of magnetic fluid acceleration sensor are studied theoretically and experimentally..
