Max Size 60mm x 60mm x 60mm, 6-Sided Symmetry We offer Large Neodymium Cubes for industrial holding, scientific research, and magnetic separation. A large cube represents the ultimate concentration of magnetic energy. Unlike flat plates or long bars, a cube creates a deep, dense magnetic field that projects equally from its pole faces. We can produce custom cubes up to 60x60x60 mm in size. These are not toys; they are serious industrial components. Commonly used in particle accelerators, magnetic braking systems. And heavy-duty jigs where maximum force in a compact footprint is required. The Engineering Logic: The “60mm Limit” Physics dictates the maximum size of a single-piece Neodymium magnet. 1. The Saturation Ceiling: We limit our single-piece cubes to 60mm x 60mm x 60mm. The Physics: To magnetize Neodymium, we must blast it with a massive electrical pulse via a copper coil. The Reality: If a solid block is thicker than 60mm, the magnetic pulse cannot fully penetrate to the center. A 100mm solid cube would have a “soft,” un-magnetized core, leading to poor performance. Our Solution: If you need a cube larger than 60mm, we will engineer it as a Laminated Assembly (stacking smaller blocks and bonding them). Ensure full power throughout the assembly. 2. Geometric Symmetry (6-Axis Utility): The Advantage: A cube is physically identical on all sides (L=W=H). This is critical for research setups and modular fixtures. You can rotate the magnet 90° to change the field vector (X, Y, or Z axis). But not changing the mechanical setup or clamping brackets. Critical Safety Advisory A 50mm N52 Cube is a bone-crushing hazard. 1. Handling Protocol: A large cube generates hundreds of pounds of pull force. The Risk: If two of these cubes snap together with your hand in between, it will result in severe crushing injuries. Our Packing: We ship these with heavy wooden spacers and thick shielding. Assembly: You must use non-magnetic mechanical tools (jigs) to install them. Never handle large cubes by hand. 2. Pole Marking is Mandatory: The Problem: On a perfectly machined cube, you cannot tell which side is North. Our Standard: We mark the North Pole (usually with a Red Dot or “N” laser etching) on every large cube. Without this, your assembly team will have to test every single magnet, which is dangerous and slow. Ideal Applications Scientific Research: Beam steering magnets in particle physics labs. Halbach Arrays: Large cubes are the primary building blocks for industrial Halbach cylinders. Magnetic Separators: Suspended over conveyor belts to pull heavy trampoline iron. Work-Holding: Heavy-duty magnetic chucks and welding jigs. Ordering Guide: Precision & Safety To order these safely, please define: 1). Dimensions: Side Length (e.g., 25.4mm, 40mm, 50mm). 2). Marking: “North Pole Marked?” (Standard inclusion). 3). Grade: “Do you need N52 power, or is N35 sufficient?” (N35 is significantly cheaper for large blocks). 4). Separation: “Do you have the tools to separate these?” (If not, ask us to pack them individually or with extra-wide spacers). Packing Method It is important to guarantee safe transit for big NdFeB magnets. And comply with international IATA and IMDG regulations. We follow a 3-stage shielding method for all large neodymium shipments. 1). First, we put the magnets in dense foam to create a protective air gap. 2). Then, line the shipping cartons with steel plates to securely contain the intense magnetic flux. When shipping multiple pieces, we will alternate pole alignments. Neutralize stray magnetic fields. Insert sturdy spacers between the magnets. This way, we can ensure safe, pinch-free separation upon unpacking. 3). Finally, every package will undergo stringent field-strength testing before sending to shippers. Follow these 3 essential steps, we can guarantee such big strong magnets pass airline safety standards. And assure a secure and hassle-free delivery to you.
