Is Silver Magnetic? The Surprising Truth About Precious Metals
The magnet attraction test and the magnet slide test are two prevalent magnet tests. The magnet attraction test examines whether a magnet is drawn to the silver item, or in other words, if the item is attracted to a magnet. If the magnet is attracted, it suggests that the item may contain other magnetic metals and may not be authentic silver.
