Magnetic force line observer

Abstract

The invention provides a magnetic force line observer. The magnetic force line observer has the advantages of convenient use and easiness in processing, and is applicable to the observation of magnetic force line distribution. With the magnetic force line observer adopted, magnetic force line distribution can be observed intuitively and quickly. The magnetic force line observer check comprises a box body, a box cover, a plurality of compasses and compass rotation shafts; the box body and the transparent box cover constitute a sealed space; the compasses are rotationally arranged between the box body and the box cover through the compass rotation shafts which are in one-to-one correspondence with the compasses; and the compass rotation shafts are parallel to each other. The box body and the box cover constitute the sealed space, and therefore, the magnetic force line observer has dustproof and waterproof effects. When the magnetic force line observer is used, the magnetic force line observer is made to approach a measured magnet, the plurality of compasses deflect by different angels under the action of the magnetic force lines of the measured magnet; and through observing the deflection situations of the plurality of compasses, a user can master the magnetic force line distribution pattern of the measured magnet. The magnetic force line observer has the advantages of convenient use and easiness in processing. With the magnetic force line observer adopted, magnetic force line distribution can be observed intuitively and quickly.

Description

technical field [0001] The invention relates to a device for measuring the direction of a magnetic field, in particular to a magnetic force line observer. Background technique [0002] In the manufacturing process of industrial magnets, it is often necessary to observe the distribution of magnetic force lines conveniently in order to judge the quality of magnets qualitatively. At present, the instruments that can view the magnetic field lines are mainly realized by using iron powder, iron filings and other media. They are mainly used for teaching demonstrations. The scope of use is narrow and the operation is inconvenient, so they cannot be applied to industrial production. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a magnetic field line observer, which is convenient to use, easy to process, and can directly and quickly check the distribution of the magnetic line of force, and is suitable for viewing ...
