Neodymium Block Magnet - 6mm x 5mm x 3mm | N45

Neodymium Block Magnet – 6mm x 5mm x 3mm | N45 This N45 Neodymium Block Magnet delivers strong magnetic performance in a compact rectangular shape. Measuring 6mm long × 5mm wide × 3mm high, it is suitable for small assemblies, model making, craft projects and precision positioning applications where space is limited. Featuring a nickel-coated finish, this Rare Earth block magnet has a stated pull force of 1.27kg and a surface magnetic flux density of 6,486 Gauss. It is magnetised through its 3mm height, placing the North and South poles on the opposing 6mm × 5mm faces. Key Features N45 Neodymium: Strong Rare Earth magnetic material for compact applications. Small rectangular profile: Easily incorporated into recesses, housings and custom assemblies. Nickel coating: Provides a smooth metallic finish and helps protect the magnet’s surface. 1.27kg stated pull force: Suitable for small holding and attachment tasks, subject to application conditions. Magnetised through height: Magnetic poles are located on the two largest faces. Applications This 6mm × 5mm × 3mm Neodymium block magnet is suitable for: Model making, miniatures and hobby projects. Small magnetic closures for boxes and enclosures. Positioning and alignment in prototypes. Craft, display and lightweight attachment applications. Integration into compact components and custom assemblies. Specifications Material: Neodymium Rare Earth Grade: N45 Length: 6mm Width: 5mm Height: 3mm Coating: Nickel Stated pull force: 1.27kg Stated surface flux density: 6,486 Gauss Magnetisation direction: Through the 3mm height Pole faces: Opposing 6mm × 5mm surfaces Handling & Performance Neodymium magnets are brittle and require careful handling. Avoid allowing magnets to snap together, as impact can cause chips or breakage. Keep small magnets away from children. Pull force is a guide rather than a safe working load. Actual holding strength depends on the steel surface, contact area, air gaps, temperature and direction of loading. Test the magnet in your intended assembly before use. Frequently Asked Questions Where are the North and South poles located? The poles are on the opposing 6mm × 5mm faces because the magnet is magnetised through its 3mm height. Can this magnet hold 1.27kg in every application? The stated pull force does not guarantee the same holding strength in every setup. Surface coatings, gaps, steel thickness and sideways loading can reduce performance. Is this magnet suitable for a small magnetic closure? Its compact block shape makes it suitable for small closure designs. Confirm the required holding strength and secure the magnet appropriately within your assembly.
