Our self-adhesive neodymium (NdFeB) disc magnets are available in two types - one with a North pole visible (/N versions) and one with a South pole visible (/S versions).
If you are using these magnets to magnetically attract mild steel surfaces then either the North or the South versions can be used - for note they will give the same pull force as each other (sometimes arranging in a -N-S-N-S- arrangement may give a slight boost to performance.
If you want to use these magnets to attract to each other, for example to close a cardboard folder, you will need a North pole version to attract a South pole version (unlike poles attract).
Note that the side with the 3M 468 adhesive backing is also magnetic with the polarity opposite to that stated for the magnet (i.e. the North visible version has a South pole on the adhesive side; the South visible version has a North pole on the adhesive side) - this information may be useful to those wishing to hide magnets away in their product (such as folding over - ensure unlike poles are facing each other for attraction between magnets).
Supplied with either a keeper or in in rows with a keeper at each end.
Our neodymium (NdFeB) adhesive backed disc magnets are nickel plated unless stated otherwise. Other sizes, shapes, grades and coatings (such as black epoxy) are available upon request. Neodymium adhesive backed disc magnets with higher operating temperatures can be supplied by special request but the adhesive may fail at the higher temperatures (unless you are using the high Hci for resistance to demagnetisation from external magnetic fields).
IF YOU WOULD LIKE A DIFFERENT SIZED OR SHAPED ADHESIVE BACKED MAGNET, PLEASE CONTACT US BY EMAIL FOR A QUOTATION - WE CAN SUPPLY ROUND, SQUARE, RECTANGULAR, THICKER, THINNER, LARGER OR SMALL SIZES, DIFFERENT MAGNET GRADES AND MAGNET TYPES AND ALSO WITH DIFFERENT COATINGS (E.G. BLACK EPOXY, BLACK NICKEL, ZINC, ETC) OR PLEASE CALL US ON +44 (0)114 225 0600
