Nested coil configurations

Definition

Nested coil configurations refer to a specific arrangement of multiple coils, where one coil is placed inside another, allowing for enhanced magnetic field generation. This design is particularly important in high-field magnets, as it maximizes the magnetic field strength while maintaining stability and uniformity across the field. The integration of nested coils enables efficient current distribution and reduces the overall size of the magnet system.
