The Discovery of the TRUE 3D Magnetic Field - Halbach Array | Magnetic Orbitals https://www.youtube.com/watch?v=MJnod3UFN6w "For the first time in history, the true 3D magnetic field of a Halbach array has been experimentally mapped and reconstructed using magnetic field tomography with a precision Hall-effect sensor. The Halbach array is one of the most important magnetic configurations in modern engineering. It is used in electric motors, brushless motors, magnetic levitation systems, particle accelerators, MRI systems, and high-efficiency generators because of its unique ability to concentrate magnetic flux on one side while canceling it on the other. Until now, its magnetic field has only been represented through simplified 2D diagrams and textbook field lines. In this video, Marsio Salcuni applies the Magnetic Orbitals method to reconstruct the full three-dimensional structure of the Halbach array magnetic field, revealing hidden polarity merging, interaction zones, and geometric transformations occurring over millimeter-scale distances. Through fixed-angle magnetic measurements and a complete magnetic “CT scan”, the field is visualized layer by layer, exposing structures that traditional representations cannot show. This experimental reconstruction provides deeper insight into magnetic flux concentration, field asymmetry, dipole interactions, and practical magnetic engineering applications."
