ABSTRACT:
An annealing furnace for annealing magnetic cores therein. Each magnetic core is placed on a tray on which the core is transferred on rollers through the furnace along with a conductive magnetizing conductor or shaft positioned inside the core and a current source for supplying a current to the conductive magnetizing shaft. After the tray, core and current source pass through the furnace, the annealed core is removed from the tray, and the tray and current source are returned to the furnace entrance for reuse with another core.
