1. Strong magnetic field: Halbach arrays produce a strong, uniform magnetic field, which is useful in many applications that require high magnetic forces.
2. Efficient use of magnetic material: Halbach arrays use less magnetic material than traditional magnet arrays, making them a cost-effective solution for many applications.
3. Reduced magnetic field on the opposite side: Halbach arrays exhibit a sharp drop in magnetic field on the opposite side of the array, reducing interference with other nearby magnets or objects.
