DEFINITION

Classification: 335/217

(under subclass 209) Subject matter wherein the magnet or electromagnet is designed or constructed to change its operating characteristics responsive to variation in temperature, or includes temperature responsive elements to effect such a change.

(1) Note. The temperature responsive element may be, for example, a temperature sensitive biasing means or a portion of the magnet such as, for example, a shunt means or the core may include temperature sensitive material.

(2) Note. The temperature sensitive means may be responsive to ambient temperature or responsive to the temperature change due to current flow in the magnet.
