Adhesive disc magnet

Adhesive backed disc magnets are round coin-shaped magnets of varying diameter and thickness which have an adhesive backed layer on one pole. The adhesive layer is a 3M adhesive with a protective backing strip – simply remove the protective backing strip and press the adhesive backed Neodymium disc magnets onto the item you want to adhere to. The adhesive layer is placed on one magnetic pole. So a North described adhesive backed NdFeB disc magnet has the magnetic North pole visible and the magnetic South pole has the adhesive backing. A South described adhesive backed Neodymium disc magnet has the magnetic South pole visible and the magnetic North pole has the adhesive backing.

When using the magnets to attract a ferromagnetic surface, either type of NdFeB adhesive backed disc magnet can be used. Sometimes, if the magnets are spaced apart near enough to each other, you could consider using alternate Norths and Souths as this may possibly give a small boost to performance.

In some applications the magnet is hidden. So knowing how you want the magnets placing in the final assembly could affect the polarity you need for your magnets. Such NdFeB adhesive backed disc magnets are very popular with the printing, packaging and arts and crafts industries as well as for use in the office and at home.
