Zusammenfassung:	PROBLEM TO BE SOLVED: To resolve such a problem that as an iron content detecting method in the conventional water granulated slag, there are an electromagnetic separation method, atomic absorption method and electromagnetic induction method, but particularly, in the electromagnetic induction method, the detecting accuracy is different according to a coil shape, exciting frequency, phase, etc. SOLUTION: In the detecting method of the iron content in the water granulated slag so as to detect the iron content in the water granulated slag 6, a sample case 3 holding the water granulated slag 6 into a cylinder 7 fitting an exciting coil 1 and a detecting coil 2, is inserted. The exciting frequency having 1 kHz-20 kHz, is impressed into the exciting coil 1 and excited, and the iron content is detected by the outputted voltage obtd. from the detecting coil 2.
