BASIC ATTRACTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a basic attraction structure which is capable of easily generating a magnetic flux and improved in energy efficiency. SOLUTION: A basic attraction structure is equipped with a composite magnet 3 provided with a permanent magnet 1 with a pair of edge faces 1c and 1d opposite to each other in polarity, and electromagnets 2 magnetically connected to the edge faces 1c and 1d of the permanent magnet 1. The basic attraction structure makes the one surface of a part of the composite magnet 3 locating the permanent magnet 1 therein serve as a magnetism working surface 6, and makes the other surface of the composite magnet 3 substantially opposed to the above working surface 6 serve as a non-magnetism working surface 19. The side of the permanent magnet 1 located on the magnetism working surface 6 side of the composite magnet 3 is shorter than the other side of the magnet 1 located on the non-magnetism working surface 19 side of the composite magnet 3.
