5 Data storage The magnetic strip has long been used in data storage and a common example is the information stored via a strip on the back of a credit card This strip stores information by rearranging the particles on a piece of magnetic material
[email protected]A pocket compass uses a magnetic needle to show which way is north the dark magnetic strip on the backside of a credit card stores data in much the same way as a computers hard drive does vacuum cleaners blenders and washing machines all have electric motors that work by magnetic principles

In this method of magnetic separation we use the magnetic properties of certain metals to divide them from the nonmagnetic gangue here we place the powdered ore on a roller belt one belt of this roller is a magnet so the magnetic material attracts to the metal belt and stays on the belt the nonmagnetic gangue falls in a heap from the belt
