Components of mixtures can be separated in many ways. The method that is being used usually depends on the type of mixture. Metal and non- metal objects can be separated by using a magnet. There is no chemical reaction involved in the separation of components.
Metals which are made up alloy, nickel, or cobalt are easily attracted to the magnet, while non-metals are not. Iron fillings, thumb tacks, staple wire, pins, coins, and needle are some common examples of objects that are attracted to the magnet. When they mixed with non-metals, these could be separated by magnet.
