Both silver and gold are diamagnetic metals and are not attracted to magnets but the combination of silver with other metals in non standard limits causes the grade of silver to change and become a silver alloy and the combination of other metals with silver is done more than usual and standard Basically a pseudo silver composite metal appears and such a composite metal is no longer good silver or pure silver and the discriminating metal detector or the discriminating detector has the ability to detect and discriminate the silver alloy especially the frequency metal detector or the frequency detector that has the number of VDI and Threshold of surface and Size
