Grand cylindrical neodymium magnet 30 mm x 5 mm, set of 12 — Grand

Set of 12 cylindrical neodymium magnets from Grand, each magnet measuring 30 mm in diameter and 5 mm in thickness. These permanent rare-earth magnets deliver high magnetic strength in a compact cylindrical form, suitable for applications that require reliable magnetic holding power in a small footprint. The set provides multiple identical magnets for repeated use or projects that need several magnetic elements.

Advantages

High magnetic strength relative to size ensures secure fastening and efficient holding in many applications. Uniform dimensions across all 12 pieces simplify planning and installation. The cylindrical shape offers a flat, stable contact surface for attachment to ferrous materials and easy alignment when combining multiple magnets. Durable coating reduces corrosion risk in typical indoor environments and extends usable life when handled and stored correctly.

Suitable for

• DIY projects and home repairs
• Model building and craft work
• Magnetic experiments and educational demonstrations
• Temporary mounting and fixtures in workshops or offices

Key specifications

• Shape: cylindrical
• Material: neodymium (rare-earth permanent magnet)
• Diameter: 30 mm
• Thickness: 5 mm
• Quantity in set: 12 pieces
• Surface: coated for corrosion resistance (typical for neodymium magnets)

How to use

Select a clean, flat ferrous surface or pair magnets with suitable metal plates to achieve the desired holding configuration. For mounting, position the magnet so the flat face contacts the metal surface; for stacking or combining magnetic force, align poles carefully to avoid sudden attraction. Use non-magnetic spacers or adhesive fixings where permanent attachment is required. Keep fingers and tools clear of the contact area when multiple magnets are allowed to snap together to avoid pinching.

Usage recommendations

Store magnets separated or with magnetic spacers to minimize attraction between pieces. Avoid exposing neodymium magnets to high temperatures or corrosive environments. Keep out of reach of children and electronic devices sensitive to magnetic fields. When handling multiple magnets, work on a protective surface and use gloves if necessary to reduce the risk of injury and surface damage.
