  • Learn how to generate electricity by means of induction

    Michael Faraday, an English scientist, accidentally discovered that instead of creating magnetism in a conductor through which electricity flows, the reverse is also possible in that electrical current can be generated by passing magnets against a conductor!

  • Test your friends coordination with this electrical device

    When a flash light is switched on, a simple electrical current is instantly completed as the 'electrons' flow from the batteries through the switch and bulb, and back to the batteries. The 'switch' to get the current flowing, can...
