12mm X 9mm X 4mm Neodymium Bar Magnet N35 (Length: 12mm, Breadth: 9mm, Thickness: 4mm)

12mm × 9mm × 4mm Neodymium Bar Magnet (Grade N35)

This neodymium bar magnet is made from sintered Neodymium Iron Boron (NdFeB), one of the strongest permanent magnet materials available. With a length of 12mm, breadth of 9mm, and a thickness of 4mm, this magnet offers a greater volume compared to thinner variants, resulting in a noticeably stronger pull force and deeper magnetic field penetration. The triple-layer Nickel-Copper-Nickel coating protects against rust and wear, ensuring reliable performance over a long service life.

Key Features

• Grade N35 neodymium for strong, reliable magnetic performance
• Greater 4mm thickness delivers stronger pull force and deeper magnetic field reach
• Triple-layer Nickel-Copper-Nickel (Ni-Cu-Ni) coating for corrosion resistance
• Axially magnetised through thickness for easy stacking and alignment
• Precision dimensions for consistent performance across every piece
• Suitable for both one-off projects and bulk applications

Common Uses

• Electronics and PCB assemblies
• Reed switch and sensor activation
• Robotics and engineering prototypes
• Jewelry clasps and fashion accessories
• Magnetic closures for boxes and packaging
• Holding and clamping fixtures in workshops
• DIY crafts, model making, and hobby projects
