Frequently Asked Questions

What determines the pull of a magnet?

Remanence Br. Generally, the larger the Remanence the stronger the pull.

What determines the amount of magnetic material I need for my application?

Energy product BHmax. The bigger the energy product is, the smaller the size of the magnet you need.

What determines whether a magnet will stay magnetised when I use it?

Coercivity Hc. The larger the coercivity, the stronger is the magnet's resistance to demagnetisation.

Why use Neodymium magnets?

Because they have the highest Remanence, Coercivity and Maximum Energy Product of all commercially available magnets.
