Neodymium Ring Magnet 7 x 3 x 5 mm N52 horganyzott
An NdFeB (neodymium) ring magnet provides high magnetic attraction for its size and fits readily into various holders and components. Alongside high magnetic attraction, the surface coating helps improve durability. N52 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52. The ring magnet fits readily into a recess or around a hole and can be used on a shaft or screw, or as a spacer.
At Ø7/Ø3×5 mm, this magnet is useful for magnetic catches, DIY, organisation and lighter attachments to steel. (Ø7/Ø3×5 mm) Paint, film or gaps noticeably reduce magnetic attraction. The magnet performs best on a flat, clean surface.
Warning: not suitable for children. Swallowed magnets can cause serious injuries. Seek urgent medical attention. Magnetic attraction is strong. Bring magnets together and separate them carefully to avoid pinching injuries and chipping. Keep them away from bank cards, sensitive electronics and medical devices.
