Multiphase System of Coils as Illustrated by Magnetotherapy

This paper present coil arrays. This array induces magnetic field within the human body. The aim is to obtain magnetic field of relatively high homogeneity. Instead of one coil, set of 8 coils separately fed are proposed. The results obtained by feeding the coil with different currents and different phase angle are better than result for one coil but they are not spectacular and involve some disadvantages. Every proposed solution was optimized by Particle Swarm Optimization's implementation.
