Guide on How to Choose Polarity for Adhesive Magnets
The adhesive on a magnet provides a convenient way to fix the magnet onto a surface. But most of often there is a question about which polarity do I need for my application. The rule is if you use these peel and stick magnets to attract to a steel surface, you can simply choose no preference; but if you are planning to use these magnets to attract to each other, you need choose half of your order to be north pole and the rest half of your order to be south pole; if you plan to use this magnet to attract to your own magnet, you need choose the opposite pole to match them up.
