The report describes a teletypewriter selector magnet, shielded by a housing, having a pair of electromagnets each having a radial airgap, which are mounted below opposed ends of a rotatably mounted armature. An extension of nonmagnetic material is joined to one end of the armature and extends from the housing through a slot formed therein. Shielded conductors are connected to the coils of the electromagnets to selectively energize the magnets and thereby rotate the armature in opposite directions. Modified author abatract
