PROBLEM TO BE SOLVED: To provide a magnaflux device capable of upgrading operator's work efficiency, through implement of magnaflux using a magnaflux sheet without fault and inhibition of heat generation from electromagnet compared with heretofore, and a magnaflux method using such a magnaflux device. SOLUTION: The magnaflux device includes a magnaflux sheet 10 enclosing magnetic particles within a flexible hollow body, a magnetic field generating coil 20 magnetizing test objects due to the effect of magnetic field under a contact of the magnaflux sheet 10 with a test objects, and an intermittent current generating means 40 for supplying intermittent current continuing alternately power distribution condition and non-power distribution condition to a magnetic field generating coil.
