The high uniformity coil is composed of multiple loop coils arranged along the axial direction. The more common ones are Buckler coils, Brownbeck coils, Maxwell coils, Rebes coils, and momentless coils. Compared with the Helmholtz coil, this combined coil has better magnetic field uniformity under the same diameter, can improve the uniformity of the coil in an effective space, expand the uniformity range, and is suitable for high-precision and wide-range magnetic fields.
