Abstract

A field system includes a first component having at least one first field source having opposite polarities and a second component having at least one second field source having opposite polarities. At least one of the first and second components has a movement relative to the other of the components to produce a field interaction therebetween. The at least one first and the at least one second field sources are oriented relative to each other such that in the field interaction the resulting repelling forces and attractive forces substantially cancel each other out and there is an increase and a decrease in the field strength of at least some of the field sources. Therefore, the field system, which can be a magnetic configuration system, provides a field strength change with a minimum energy input which can increase the efficiency of many machines such as MRI or electricity generators.
