Neodymium Disc Magnets:

Most disc magnets have their north and south pole on the flat circular surface (axial magnetization). The few exceptions, which are diametrically magnetized, are specifically marked.The combination neodymium-iron-boron is currently the strongest available magnet material worldwide. Even with small areas the neodymium disc magnets achieve remarkable holding power, which makes them very versatile. In our website you can find tiny, millimetre-flat magnets as well as thick discs with a diameter of several centimetres.
