The present invention relates to a demagnetization device of steel. An objective of the present invention is to allow a worker to conveniently perform a demagnetization work on site without moving the steel and to maximize a demagnetization efficiency through a demagnetization work using DC current as a plurality of electrode cables connected with a positive polarity (+) and a negative polarity (-) and an electrode rod fixed to both ends of the electrode cables are provided and an insulating jig is inserted into the both ends of the steel to insulate the electrode rod from the steel to perform the demagnetization work. To this end, according to the present invention, the demagnetization device to demagnetize the steel includes an on/off switch (110) for controlling the application state of power; a short button (112) for controlling a steel (3) by conducting current to demagnetize the steel (3); a voltage adjusting knob (120) for adjusting voltage suitably for the steel (3); a plurality of electrode cables (130) connected with the positive polarity (+) and the negative polarity (-); and an electrode rod unit (140) connected with each of the electrode cables (130) and each of the ends of the steel (3) to demagnetize the steel through current conduction. |
