摘要：
A device for deactivating a EAS marker includes a rotating support member and magnets disposed on the support member. The magnets are arranged in linear arrays, and the magnets in each array are mounted on the support member so that the upper surface of each magnet in the array has a magnetic polarity that is the opposite of the polarity of the upper surface of neighboring magnets. The support member is in the form of a thin circular platter and each array of magnets corresponds to a radius of the support member.
