Abstract

A first set of weakly magnetic elements (24) in the moving magnet element (21) are arranged to collect and concentrate the magnetic current from the permanent magnets (23) in this element, so that a concentrated magnetic current flows around the coil (26) in the fixed electromagnet element (25) via at least one essentially weak magnetic circuit including the sets of weakly magnetic elements associated with the moving magnet and fixed electromagnet elements. DETAILED DESCRIPTION - Independent claims are also included for (a) a linear electricity generating apparatus, and (b) a second electricity generator.
