Is the strong NdFeB magnet able to absorb gold and silver? This depends on the purity of the finished product of gold and silver.
For example, if a gold necklace or a silver necklace has a purity of more than 99%, it cannot be sucked. The magnet can't attract the pure gold and silver necklace, but the low-purity gold and silver necklace can be attracted. The low-purity gold and silver necklace or other kinds of finished gold and silver product will be mixed with iron, and these iron will be attracted by the magnet. If there is no iron in the gold and silver necklace, they will not be attracted absolutely.
