Power magnet, Ring 25x4x5 mm. Auto-translated (NO) If you want to pullNeodymium ring magnet Permanent magnets A strong neodymium super magnet with a hollow core in the center. The surface is very large, and the hole is only 4mm (0. 16 in. 0. 4 cm.) in diameter. Diameter: 2. 5 cm. Height: 0. 5 cm. Hole size: 0. 42 cm. Strength: approx. 9. 4 kg. Keep in mind, to achieve optimal levels of magnetism we recommend using the large surface, known as axial magnetism. This means that the magnet is magnetic on all sides, but you
