The ring magnet or toric magnet is a round drilled magnet.The magnet is made of neodymium, an iron/boron/rare earth alloy which is currently the most powerful magnetic alloy. The magnet is coated with an anti-corrosion covering (chrome and nickel alloy) to protect it from impacts and to give an attractive finish.
Neodymium ring magnet is a powerful drilled magnet with powerful magnetic strength. It is lighter than the{Lien020}
Neodymium magnets stick to any ferrous surfaces. Pull strength is significantly reduced if the magnet is not in flush contact with ferrous surface.Polarity : Magnetisation is axial when the north and south poles are located on oposing circular faces. Magnetisation is diametral when poles are located on the side of the ring.
