A method of calibrating an acceleration sensor includes suspending an inertial body using a magnetic fluid; generating a magnetic field within the magnetic fluid; modulating the magnetic field to cause a displacement of the inertial body; measuring a response of the inertial body to the modulation; and calibrating the acceleration sensor in real time based on the measurement. Current can be driven through a plurality of magnets for generating the magnetic field so as to create the modulation. Sensing coils can be used for detecting the response of the inertial body. The modulation can be periodic, an impulse or some other aperiodic function.
