Description of the Disc Magnet Neodymium magnet, the third generation of the rare-earth permanent magnet, is the most powerful and advanced permanent magnet today. The disc Magnet is one type of the neodymium. ... made of the neodymium, iron, and bonded magnetic alloy blend. The disc magnet is plated with Nickel-Cooper-Nickel coating for a shiny corrosion-resistant finish. The North and South poles are on both flat side of the magnet since magnetizing direction is Axial Magnetizing. The magnet is powerful and can be used to help stuff to stick into the iron surface. Tolerance: For each magnet, there has a tolerance to produce, as follow: +/- 0.05 mm for the small dimension; +/- 0.1 mm for the common specification; +/- 0.15mm for the big blocks. Magnetic testing As the third generation "Magnetic King", the disc neodymium magnet has its powerful pulling force. Magnetizing Direction The normal magnetizing method of the disc neodymium magnet: Axial and Radial. With the Axial magnetizing, the magnetic spread over both flat side; with the Radial magnetizing, the magnetic spread over the surround. Due to this product is a customizable product, so pls send us the specific size, the same as the picture, thanks!
