How does magnetic viewing film work？

Magnetic pole viewing sheet, also known as magnetic field visualization film or magnetic pole display card, is a tool that can visualize the distribution of a magnet's magnetic field, today we will introduce how it works and how to use it to see the magnet's direction of magnetization, the number of poles.

Magnetic viewing film working principle;

Magnetic pole viewer contains tiny magnetic particles inside, these particles will be rearranged under the action of the applied magnetic field to form patterns visible to the naked eye, the strength and direction of the magnetic field can be shown through these patterns, enabling the user to intuitively observe the position of the magnetic poles and the distribution of the magnetic field.

Tutorial on how to use magnetic viewing sheet;

Test the number of magnetization poles of the magnet: Place the magnet product in the developing area of the magnetic film to clearly see the magnetization level of the magnet product. The magnetization levels of the magnet product are even because they are all 1N1S.

Check the magnetization method of the magnet: The magnetization methods of magnet products are commonly axial magnetization and radial magnetization. The axial magnetization product can see the dividing line between the north and south poles that divides the height (i.e. thickness) of the magnet in half on the height surface, while radial magnetization does not. Radial magnetization products are evenly divided into several parts.

Whether axial or radial is to look at the side of the magnet, showing the word "+" is axial, showing "|" for radial.

Judge the magnet strong magnetic surface and weak magnetic surface: multi-stage magnetization products, a magnetic surface of the magnetic force relative to another magnetic surface to be strong or weak, in the magnetic pole test film development area, can be distinguished according to the clarity of the magnetic decomposition line, the magnetic line of the clear side of the strong magnetic surface, slightly fuzzy side of the weak magnetic surface.

The above is about the working principle and detailed use of magnetic pole observation piece (card) introduction, provided by China neodymium magnet manufacturer Courageous Magnet, need magnet quotation, processing customized samples can send us an inquiry, thank you!
