Electromagnetic yoke flaw detector

The utility model discloses an electromagnetic yoke flaw detector which comprises an electromagnetic yoke core, a shell covering the top end of the electromagnetic yoke core and a magnetic induction loop which is arranged in the shell and wound on the electromagnetic yoke core, wherein two detection ends for detecting are arranged at the bottom end of the electromagnetic yoke core; the wire diameter of the magnetic induction coil is 0.2-0.3mm and the magnetic induction coil includes 1800-2400 turns. As the magnetic induction coil which is wound by 0.2-0.3mm of lead, the electromagnetic yoke flaw detector disclosed by the utility model is quite smaller than an existing magnetic induction coil in wire diameter, can be used for reducing the current in the magnetic induction coil, saving electric energy and avoiding burn caused by high heat; meanwhile, the coil has 1800-2400 turns, which is more than that in the existing coil, so that a problem of magnetic field weakening caused by current reduction is solved.
