The size of circular countersunk hole magnet is generally expressed by large D, diameter of D1 countersunk hole, diameter of D2 straight hole, thickness (height) of H. The magnetic force of circular countersunk hole magnet defaults that the two ends are maximum magnetic surface, that is, axial magnetization.

What is the main attraction of permanent magnets?
1. Type (shape) and grade of magnet;
2. The magnetic pole area of ​​the magnet;
3. The working temperature range of the magnet;
4. The air gap between the magnet and the test steel plate. According to the finite element analysis results, the suction force of the permanent magnet decreases with the increase of the air gap, and even a small air gap will have a huge impact on the suction force. Contour, Convex T-Shape Powerful Magnet Neo

Different fields, different products design, the magnetic demand for magnets will be different, the small edition imagines that the magnet’s attraction is not only related to the size of the magnet, but also to the direction of the absorbed objects. The following diagram is a strong magnetic tension diagram. Strong Neodymium Irregular Semicircular Magnets
