Abstract: Ovens for atomic clocks may include a body including a cavity within the body. A plurality of heating elements may be distributed around the body, each heating element of the plurality including coils of electrically resistive material. An arrangement of the plurality of heating elements may be such that far fields of magnetic fields having opposite polarities induced by respective coils of the heating elements overlap.
