Magnetic observation piece of rapid detection of the number of magnet magnetization and how can I know the hand of magnet magnetization and the number of magnetization, the a lot of people don't know, Ricky magnet xiaofu card today to share with you? Magnet magnetization way of products we naked eye cannot see, only through the use of magnetic pole test piece for inspection, pole piece ( Also called magnetic card) 。 And then through the magnetic pole test tell the magnetization of magnet products. Pole piece function: using the magnetic pole test pieces to test out the magnetization series of magnet, the magnetization, strong magnetic surface and the weak magnetic surface. Pole to observe slice identification methods: test the magnet magnetization series: place the magnet products in measuring disk imaging area, can clearly see the magnet magnetization series of products, the magnet magnetization series products are an even number, because all pairs. Magnetic observation principle: magnetic piece is to use two thin film, covered by a layer of fine iron powder in between them, when close to the magnet, iron powder will be sucked into magnetic, magnetic pole line will be displayed. At that time you can see the pale white pole line. Identification of magnet magnetization: magnet product of magnetization is common for the magnetization, the magnetization to the radial and axial axial magnetization of the product at the height of the magnet surface height (as you can see the magnet The thickness) Is divided into two and a half of north and south poles line, but not for radial magnetization, radial magnetization of the product are evenly into several pieces. Identification of strong magnetic surface and the weak magnetic surface: multi-stage magnetization of the product, a magnetic magnetic below another magnetic surface relatively stronger or weaker, in the region of the magnetic pole test film developing, can according to the definition of the decomposition of magnetic force line to distinguish, clear lines of magnetic force side with strong magnetic surface, a fuzzy side for weak magnetic surface.
