It magnetism

Answer 2

One way to separate paperclips from a mixture of salt and pennies is to use a magnet. The paperclips will be attracted to the magnet and can be easily picked up, while the salt and pennies will remain unaffected. Alternatively, you could dissolve the mixture in water, as the paperclips will sink, while the salt will dissolve and the pennies will remain at the bottom.
