MAGNETISM

 

         A mineral discovered in the town of magnesia was found to have a strange property. It could attract pieces of iron towards it. This mineral is named Magnetite after the place where it was discovered. Later, it was found that magnetite is mainly composed of oxides of iron (Fe3O4 ). These are now known as Magnets. The study of magnetic properties is called Magnetism.
