CHOOSING THE RIGHT MAGNET

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.

ITíS IMPORTANT TO HAVE ACCESS TO COMMERCIAL EXPERTISE WHEN YOUíRE AT THE PRODUCT DEVELOPMENT STAGE

AMS has technical expertise inhouse and through its equity partner, CSIRO, as well as local and overseas commercially based design companies.

AMS has established strong working relationships with many Australian technical universities and research centres.

The CSIRO is the main source of technical advice. It retains an equity holding in AMS and is keen to promote the development of the magnet industry in Australia.

AMS has spent considerable time building relationships with other research establishments, including the University of Sydney, the University of Technology, Sydney, the University of NSW, the University of Wollongong, the Institute of Technology, Adelaide, the University of Melbourne and a consortium called SEMCAM.

SEMCAM was originally formed by the CSIRO, the University of Sydney and the University of Technology Sydney, with the task of assisting companies in developing electrical applications. It was recently expanded to include the University of Wollongong.

Permanent magnets offer great potential for significant advances in reducing the size of motors. They are currently used in applications ranging from Walkman head phones, microwave ovens and parts for computerised electronics.
