Want to learn some cool ways of teaching science to your kids? Then you’re at the right place. This video uses magnets and a copper solenoid to make an electric train. He takes a copper wire wound as a spring and then attaches the magnets to two ends of a magnetic substance. Your train and railway track are ready. Next he inserts the toy train into one end of the solenoid and the magnetic train traverses the length of the solenoid and comes out at the other end. He arranges the solenoid in different pattern and makes the activity even more fun for the kids.
