FREE HOLDING METHOD OF COMMODITY

摘要

PURPOSE:To secure the material easily and freely by placing the material on a magnetic powder then applying the magnetic field to secure the magnetic powder material. CONSTITUTION:The material 6 is placed in the magnetic powder material 5 contained in a container 4 with the predetermined attitude. The magnetic powder material 5 is preferably made of the magnetic material such as iron or nickel. An electromagnet 3 is placed around the container 4, and the magnetic field is applied by closing a switch S and supplying the current from the power source 1 to the coil 2 thus to secure the magnetic powder material. In such a manner the material 6 can be secured with the required attitude.
