MAGNETIC FORCE CONTROL DEVICE AND MAGNETIC BODY HOLDING DEVICE USING SAME

摘要

A magnetic force control device includes a magnetic flow generating section configured to be freely rotatable to at least define a first arrangement state and a second arrangement state and including a permanent magnet, a magnetic flow section having at least one interaction surface and including at least one pole piece made of a magnetic material in which a magnetic flow is formed therein, the pole piece is disposed such that an effect of a magnetic flow from the magnetic flow generating section on the interaction surface is minimized when the magnetic flow generating section defines the first arrangement state, and the effect of the magnetic flow from the magnetic flow generating section on the interaction surface is maximized when the magnetic flow generating section defines the second arrangement state; and at least one coils wound around the pole piece.
