High Uniformity Combined Helmholtz Coil for Precision Magnetic Field Applications
Introduction
A high uniformity coil is composed of a combination of multi ring coils arranged along the axis, commonly including Buckle coils, Brownbeck coils, Maxwell coils, Ribes coils, and moment free coils. Compared with Helmholtz coils, this combination coil has better magnetic field uniformity at the same diameter, which can improve the uniformity of the coil in an effective space, expand the range of uniformity, and is suitable for high-precision and large-scale magnetic field requirements.
