Title:
MAGNETIZATION HEAD AND MULTIPOLAR MAGNETIZATION DEVICE
Document Type and Number:
Japanese Patent JP2018073986
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetization head and a multipolar magnetization device, including a high magnetization efficiency and high versatility.SOLUTION: A magnetization head 1 comprises: a yoke 10 formed by a magnetic material; an excitation coil 40 wound around a magnetic part 12 of the yoke 10; first and second yoke supporting members 20 and 30 each of which supports the yoke; and a yoke head 50 attached to the first and second yoke supporting members 20 and 30 so as to be opposite to a magnetized body 6. The yoke head 50 is formed by the magnetic material, and is provided at a position separated from the yoke 10, covers the circumference of a tip 121 of the magnetic part 12 of the yoke 10 opposite to the magnetized body 6, and has a penetration hole 52 penetrating a region where an end surface of the tip 121 of the magnetic part 12 of the yoke 10 and the magnetized body 6 are opposite.SELECTED DRAWING: Figure 3
