    • Magnets 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.
    • Magnets are used inside a generator to transform mechanical energy to electrical energy where there are other kinds of motors which use magnets to change electrical energy to mechanical energy.
    • Electrically charged magnets can help cranes to move large metal pieces.
    • Magnets are used in filtering machines which separates metallic ores from crushed rocks.
    • It is also used in food processing industries for separating small metallic pieces from grains etc.
    • Magnets 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.
    • At home, you use magnets when you stick a paper on the refrigerator in order to remember something. Attaching a magnetic bottle opener to the fridge can come in handy.
