The invention discloses a magnetic liquid acceleration sensor, belonging to the technical field of inertia sensors and solving the problems that the weight is heavy, the measuring range is short, the sensor fails due to the fact that magnet is demagnetized because of long-time use and the stability of the sensor is reduced due to the fact that magnetic particles are aggregated because of long-time work failure in a traditional magnetic liquid acceleration sensor are solved. A cylindrical magnet (5) of the magnetic liquid acceleration sensor is a rubber magnet; the cylindrical magnet (5) is placed in a casing (2); magnetic liquid is filled into the casing (2) and is attached to two axial ends of the cylindrical magnet and enables the cylindrical magnet to suspend; a left end cover (1) and a right end cover (6) are respectively in threaded connection with two ends of the casing; a first coil (3) and a second coil (4) are respectively wound in two annular grooves of the casing; the first coil is connected with t
