Gapped Magnetic Core

Assembly

Core whose limbs are split into packets by non-magnetic gaps, so the inductance is set by the gaps and the reactor draws a stable, nearly linear magnetising current. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
