Abstract
Provided is a magnetic clamp device that is capable of more finely measuring an induced voltage generated in a coil and selecting countermeasures against reductions in magnetization force. Multiple magnet blockseach comprising an invertible magnet, the polarity of which can be inverted, and non-invertible magnet, are positioned on a surface of a plate PL composed of magnetic body magnetically clamping a mold M, Mwhen in a magnetized state. The magnetic flux traversing the invertible magnet; and a control devicethat determines whether or not there has been a polarity inversion in the induced voltage detected from the coil, and if there has been a polarity inversion, warns that the adhesion of the molds M, Mhas decreased.
