Which Magnet Suits Your Needs?

Which Magnet Suits Your Needs? - AMF Magnets New Zealand

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?
