Circular halbach array equation
WebThe circular Halbach array is composed of twelve NdBeB grade 52 arc-segment magnets with magnetizations alternating between axial and circumferential (Halbach, 1985). The … WebHalbach [20] has shown that a directed magnetic field similar to that created by the field coils can be generated using a circular array of permanent magnets. These configurations produce a uniform magnetic field inside the array and a vanishing field outside, such that the field is con- tained within the magnet ring.
