The size, size, grade, etc. of the magnet are not fixed. For example, this kind of screw hole magnet for fixing, the size is determined by you, and it can be customized according to your requirements.
Price of neodymium magnets is calculated according to the actual size, the unit is mm, do not buy only based on the imagined size, the large quantity is the best price.
Note: The magnet is divided into N and S poles, and the principle of different shapes attracting the same sex and repulsing each other, so it is necessary to prevent hand injury when using it according to the installation.
