Hello, everyone. I'm Courage Magnet Xiaofu. Welcome to our website to view the magnet pictures, understand the knowledge of magnets and the price of magnets. If you have magnet problems, you can always consult our online customer service.
We all know that magnets can be punched, as we have mentioned before, today we mainly tell you about the main role of magnets with small holes in the middle and various pictures.
What is the main function of a magnet with a small hole in the middle?
This role is a lot, not certain. For example, some product designs require a hole in the middle or side of the magnet for installation, some may be due to the need to install a screw fixed somewhere, some may need to add a small steel shaft in the middle of the motor or other places, and so on.
What are the types of magnets with small holes in the middle?
Magnets can be made into a small hole in the middle of the disc, a small hole in the middle of a square, a hole in the middle of a cylinder, a magnetic tile(Arc) hole, a small hole on the side of the ring, etc. The material can be quoted free of charge according to customer requirements.
