1.	Applications of magnetism in different field of science
Answer» \tWe might be using computers in our day to day lives but never wondered the presence of a magnet inside it. Magnetic elements present on a hard disk helps to represent computer data which is later ‘read’ by the computer to extract information.\tMagnets are used inside TVs, Sound speakers and radios. The small coil of wire and a magnet inside a speaker transforms the electronic signal to sound vibrations.\tMagnets are used inside a generator to transform mechanical energy to\xa0electrical energy\xa0where there are other kinds of motors which use magnets to change electrical energy to mechanical energy.\tElectrically charged magnets can help cranes to move large metal pieces.\tMagnets are used in filtering machines which separates metallic ores from crushed rocks.\tIt is also used in food processing industries for separating small metallic pieces from grains etc.\tMagnets are used in MRI machines which are used to create an image of the bone structure, organs, and tissues. Even magnets are used to cure cancer. Hi anchal
