Didn't expect it? NdFeB magnets can also be used in the quality inspection of hardware products. Let DEKO introduce to everyone.
1. First observe the appearance of the outline, pay attention to whether the color and profile of the NdFeB magnet frame are the same, whether the magnet color is uniform, and whether the distribution is reasonable. The surface of neodymium iron boron magnets is usually shiny and tough.
2. Prepared a pure copper pipe as thick as possible. Then prepare a neodymium iron boron magnet into the copper tube.
3. The welding of the strong magnet depends on whether the welding position is flat, whether there are cracks, whether the inner and outer corners of the joint are clean and beautiful, the diagonal size and the diagonal size of the strong magnet should not exceed 3 mm when measured with a square ruler. The smaller the diagonal difference, the finer the display process, which is also conducive to installation. electronics magnet is your good choice.
4. When the neodymium iron boron magnet enters the copper tube, it will actually fall slowly instead of getting faster and faster as usual.
The hardware quality of the powerful magnet also has a certain impact on the life of the magnet. The hardware used should look thick, the surface gloss should be good, the protective layer should be dense, and there should be no scratches. The most important point is that the opening should be flexible.
5. Adjust the camera lens to see that the magnet drops very slowly, as if something is preventing it from falling.
6. The principle is: the cross section of the copper tube is relatively thick. When the magnet falls, the copper tube will generate current, but the generated current will generate a magnetic field and prevent the magnet from falling rapidly, which is the Lenz theorem often mentioned in physics. If the copper tube is infinitely long, theoretically it will move at a constant speed. electronics magnet is your good choice.
