The rare earth element of neodymium makes the 4x25mm cylinder (rod) magnets stronger. According to the grade, the magnet-to-steel plate pulling strength varies from 1.32 lb to 1.96 lb. Due to the slender shape, neodymium rare earth cylinder magnets 4x25mm are fragile, they must be used carefully. Nickel, epoxy, and gold are common coatings for 4x25mm neodymium cylinder (rod) magnets. 4x25mm rod magnets of neodymium are ideal for DIY projects, whiteboard fixing, and also for fixing tissue boxes on the roof, etc.
