Our neodymium adhesive magnets offer the high performance of neodymium coupled with the sticking power of 3M 468 adhesive. Each magnet is supplied with a peel off backing to reveal the 3M adhesive. Our adhesive magnets are available with a magnetic north face showing or a magnetic south face showing. If the magnet is sticking to a steel surface, you can use either a north or south pole magnet. They are equally as strong. If you want to use two of these to stick to each other, for example to close a cardboard folder, you need to use a north pole and a south pole magnet so that they attract each other (otherwise they will repel).
