3.The main types of pot neodymium magnets
7. Block shap with one or two countersunk hole
Depending on the requirements of your installation,you can choose the appropriate type.

4.Grade of NdfeB Magnet:
If your application is at room temperature only,the N series is the best choice,with a max operating temperature 80 degrees Celsius. In the N series,the N55 grade has strongest magnetic force,and is also the most expensive. Generally speaking,the N35 grade is relatively cost-effective and also have strong magnetic force.But which grade to choose depends on your pursuit of magnetic force or say application.
The higher the temperature of resistance of the magnet,the more expensive it is.For example,N35 grade and N35M grade have the same magnetic force,but the max opearting temp. of N35M is 100 degrees Celsuis
