Choosing The Right Magnet

We realize you may not purchase magnetic products every day or even know which magnet is best for your application. We don’t believe a degree in Physics should be required to figure it out, either. With Master Magnetics, you have magnet experts on your side!

We’ve outlined a few things to consider before making your next magnet purchase. And if you need help, just contact us - we’re standing by.

 How will the magnet be used?

A magnet’s application is one of the most important things to determine. Think about how and for what purpose your magnet will be used.

  • Do you need your magnet to hold, lift or retrieve?
  • Will it need to push or separate?
  • Is it intended to organize, store, hang or clear areas of debris?
  • Something else?

Supporting visuals are extremely helpful. Feel free to send us drawings, sketches, photos or any other information to help us help you find the best magnet for your needs.

Where will your magnet be used?

Think about the space your magnet needs to fit, as well as the space around it.

  • What is the length, width, height or diameter required?
  • Will a standard shape such as a block, disc, or sphere fit - or is the space irregular?
  • Is the surface rough, flat, smooth or porous?
  • Does the magnet need adhesive on one side?
  • Are there any weight restrictions or requirements?
  • How much space will there be between the face of the magnet and what it needs to attract? (air gap)
  • Do you plan to use the magnet indoors, outdoors or both? 

What type of magnet material you need?

Several types of magnetic materials are available and each have different physical and magnetic properties. If you’re not entirely sure,

  • Flexible
  • Ceramic (strontium ferrite)
  • Alnico (AlNiCo - aluminimum, nickel, cobalt)
  • Samarium Cobalt (Sm Co)
  • Neodymium (Nd Fe B)

What temperature range will the magnet need to tolerate?

Will your magnet be exposed to extreme heat or extreme cold?

How strong does your magnet need to be?

The application will determine the strength of the magnet you need. Raw material magnets are rated by mega gauss oersteds, or more commonly, gauss. Magnetic assemblies are rated by pounds of pull.
