A device for deactivating a magnetomechanical EAS marker includes a coil and circuitry for energizing the coil to generate an alternating magnetic field. The coil is wound around a magnetic core. The core may be cruciform with four arms, on each of which a respective coil is provided. Alternatively, the core may be generally square and planar, with two coils wound around the core in different respective directions. |
