AI Technical Summary
In existing technologies, there are blind zones in the magnetic field superposition area and the magnetic field gradient in the edge area is low, which makes it difficult to meet the high requirements of magnetic separation and magnetic manipulation, and the edge effect is serious.
The micro electromagnet units arranged in a honeycomb array, through a hexagonal close-packed structure and gradient current distribution, combined with an outer electromagnetic ring and magnetic shielding layer, achieve uniform magnetic field distribution and gradient control, eliminating magnetic field superposition blind zones and edge effects.
It achieves high uniformity and gradient distribution of the magnetic field in a specific area, meets the high requirements of magnetic separation and control, and improves the efficiency and accuracy of magnetic separation.
