The strength of a magnet can be measured in a number of ways. A magnet’s Gauss value (flux density) and maximum pull strength are both commonly quoted. Here, we have grouped our range by their maximum pull strength, the maximum weight each magnet can support vertically when in flush, direct contact with a steel surface of equal thickness.

Small Strong Magnets

In this section you will find our smallest neodymium and samarium cobalt magnets that are all surprisingly strong for their size. You will also find our range of great value ceramic magnets and flexible sheets and tapes.

Very Strong Magnets

Browse the categories below for our medium-sized rare earth magnets in a variety of shapes including pot and clamping magnets. Here, you will also find our larger alnico and ceramic magnets.

Super Strong Magnets

The industrial magnets in the categories below are all classed as super-strong. They are designed to provide the maximum clamping force for their size and attract ferrous objects over large distances.

Measuring Magnet Strength

All our ranges are tested using computer controlled tensile and compression machinery, which accurately measures the weight a magnet can support vertically when in flush, direct contact with a steel surface. It is also able to test a magnet's pull strength when attracting a steel surface through varying air gaps. Using thorough measurement techniques and the best testing equipment we make sure you always get the right magnet for your purpose.

As well as pull strength, we also list the Gauss rating of our magnet's in each product’s technical specifications table. The Gauss measurement represents the density of the magnetic field emitted by a magnet, the higher the Gauss rating the deeper the magnetic field produced.
