PROBLEM TO BE SOLVED: To make compact a magnetic body carrying device or a magnet used therefor by making the magnet whose magnetic N and S pole widths and magnetic flux levels are different and which is applied with asymmetrical spiral magnetization. SOLUTION: In the case where a magnetic body 9 has a dia. A, lead angle of 45 degrees, and two line asymmetrical sprial magnetic poles, when the lead length is (a), the magnetic pitch becomes 1/4a and 3/4a or so. The pitch can be adjusted by the winding width of copper wire of magnetization coil. When the length of magnetic body 12 attracted to a magnetic pole 10 through a nonmagnetic outer cylinder 2 is 1/2a, the body 12 is attracted by the pole 10 moving in association with the rotation of the rotating magnetic body 9 in the direction of arrow 13 and moved to the direction of arrow 14. With the magnetic flux of the pole 10 strong, a long magnetic body can be conveyed. |
