Magnet in life - small phone magnet
Look around your house and in your everyday routine for magnets. Refrigerator magnets are not the only ones! Magnets are all around you. Smart Phones use small magnets to interact with a coil of wire to create the vibrate function. Without magnets they would not vibrate. Blackberry phones often have a magnet in their protective pouch which tells the phone to sleep when it is returned inside the pouch.
