MAGNETIC ELEMENT |
摘要 |
A magnetic element comprising an operation portion having a length L which undergoes a steep change in magnetization with a change in external magnetic field and at least one pair of control portions having a coercive force that is higher than that of the operation portion. The control portions are arranged so that a magnetic pole of each of the control portions is generated within a range of not more than 0.3L from the end of the operation portion, and the control portions are not present within a range of up to 0.2L from the center of the operation portion. The magnetic element of the present invention has a small size and good magnetic characteristics. Furthermore, it has a simple structure that is easily prepared. Moreover, the magnetic characteristics of the magnetic element of the present invention are highly reproducible.
