PROBLEM TO BE SOLVED: To provide a lifting magnet device and perform properly an alarm indication with the magnet device. SOLUTION: A lifting magnet device 31 is equipped with a first 32 and a second DC converter 33 connected in parallel in opposite polarities, and with these DC converters, a lifting magnet 34 is connected in parallel. With this lifting magnet, an alarm indication circuit 41 is connected consisting of a rectifier part 42 to rectify the voltage impressed on the lifting magnet to generate a rectified voltage and a voltage stabilizer circuit part 43 to adjust the rectified voltage into a predetermined voltage. An indicator light 44 is connected in parallel with the voltage stabilizer circuit part.
