Abstract
The magnetic energy stored in a cylinder or torus is optimized by adopting a special current distribution with helical windings. A cylindrical cable wound following a Bessel‐function distribution that reverses on the surface has greatly reduced self‐force and self‐stresses. This result applies to energy storage in large‐scale superconducting magnets, and is also of importance in plasma physics and astrophysics.This publication has 12 references indexed in Scilit:
