Your choice of Magnet will largely depend on what your application is.
Some points to consider include are:
- If the magnet is being used for holding or lifting something, what pull force do you require?
- What is the operating temperature?
- How far does the magnet need to operate, i.e. distance of the magnetic field?
- Will the magnet be used in liquid or in an environment with high moisture levels?
- Does the magnet need to be flexible?
