Separating mixtures using magnet

Description

                            Have you experienced that your pins mixed up with your talc powder? What technique of separating the pins from the talc powder? Have you tried using a magnet in separating them? Magnetic separation one of the ways to separate mixture of metals from non-metals.

                       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.
