Abstract
The present invention relates to a magnet having a linear magnetic flux density, which causes the magnetic flux density thereof to vary linearly and, more particularly, to a magnet having a linear magnetic flux density, in which the shape and magnetization pattern of the magnet are changed so that displacement in proportion to linearly varying displacement from the magnet is more accurately measured using a magnetic flux sensor, thus causing the magnetic flux density to vary linearly (or rectilinearly) according to the displacement. The present invention is configured to have a rectangular shape or a trapezoid shape so that displacement in proportion to linearly varying displacement from the magnet is more accurately measured using a magnetic flux sensor, and is configured such that the value of magnetic flux density varies linearly (rectilinearly) according to the magnetization pattern of the rectangular shape or a trapezoid shape.
