Abstract:
A magnetic field gradient is generated in a space, and a microparticle is flied downward in the space, thereby applying a magnetic force from the magnetic field gradient onto the microparticle. Then, a velocity and an acceleration of the microparticle due to the magnetic force are measured, thereby measuring a mass of the microparticle on the measured velocity and a magnetic susceptibility of the microparticle.
