METHOD OF MANIPULATION BY ROTATIONAL MAGNETIC FIELD

摘要

A rotational magnetic field is applied to substrate (7) exhibiting any magnetism among paramagnetism, ferromagnetism and diamagnetism and, superimposed thereon, material (6) containing magnetic particles wherein at least one magnetic particle exhibiting any magnetism among paramagnetism, ferromagnetism and diamagnetism is contained. Consequently, the magnetic dipole within the magnetic particle is rotated, and, by the magnetic dipole-magnetic dipole interaction between the magnetic particle and the substrate, the material (6) containing magnetic particles wherein the above magnetic particle is contained is moved on the substrate (7). Thus, there is provided a method of manipulation by rotational magnetic field whereby easy and inexpensive manipulation can be performed.
