Magnets are very use full for example they can help attract medal for men who work at a recycling center and another example how magnets can be used is in a train in Shanghai China that moves with magnets.It moves with magnets because on the bottom of the train their is a negative charge and on the train track it has a negative charge so if both the train and the train track have a negative charge than they push each other away from each other and that is how the train can move.If you get a piece of magnet and rub in on the sand like if it was sup than it will make black stuff.
