Abstract
PURPOSE: To detect an electric current with a detector of a simple construction and display the result of detection such that it can be seen easily from a distance, by attaching a heat sensitive element to a magnetic element which generates heat by an induced current, and detecting an electric current, which flows in a conductor, with reference to a change in the color of the heat sensitive element.
CONSTITUTION: An AC current flowing in a conductor 1 causes an AC magnetic field to be generated therearound. The AC magnetic field causes magnetic induction to occur in a magnetic element 3A. The magnetic element 3A generates heat due to the induced current. The heat generated by the magnetic element 3A causes a heat sensitive element 3C via an insulating element 3B. The color of the heat sensitive element 3C is changed in accordance with the temperature thereof. The electric current flowing in the conductor 1 can be detected with reference to the color of the heat sensitive element 3C.
