Abstract: A self regulating heater comprises a non-­conductive, magnetic core (20) having a coil (22) wound about it and providing pole pieces (26, 28) extending into contact or very near contact with a surrounding ferromagnetic member (36) which in turn may be surrounded by and in intimate contact with a non-magnetic low resistance member (30); the magnetic member having an effective Curie temperature at the temperature to be maintained.
