Unofficial Alpha Subclasses: R H S
DEFINITION
Classification: 338/32
(under subclass 13) Subject matter wherein the resistance element includes material whose resistance value is dependent on a magnetic field applied directly thereto, or together with means for applying or facilitating the application of a magnetic field to this material of the resistance element; or wherein a resistor is mechanically linked with the magnet of a magnetic compass to be actuated by this magnet.
SEE OR SEARCH THIS CLASS, SUBCLASS:
43, for resistors responsive to inertia devices, such as a gyro compass.
103+, for a compressible type resistor with an electromagnetic operator.
116, for mechanically variable resistors generally with an electromagnetic operator such as an electric motor.
