Tidal energy devices use the natural rise and fall of coastal tidal waters caused principally by the interaction of the gravitational fields of the Sun and Moon. The tide moves a huge amount of water twice each day which can be harnessed to drive turbines which power generators to produce electricity. Although tidal energy is plentiful, a major drawback is that it can only be generated when the tide is flowing in or out, which only happens for approximately ten hours each day. Magnetism for kids - A simple introduction. By Chris Woodford.
Last updated: October 16, 2016. Science is our understanding of how the world works—and generally the world works fine whether we understand it or not. Take magnetism, for example. Magnetism for Kids. Facts About Magnetism for Kids. From your clothes to your desk, every bit of matter is made of tiny particles called atoms.
Atoms have negatively charged electrons that spin around them. Most of the time, the electrons spin in random directions. When the electrons all spin in the same direction, though, they create an invisible force known as magnetism. Alliantenergykids. Kids science: Magnetism. Science >> Physics for Kids Magnetism is an invisible force or field caused by the unique properties of certain materials.
In most objects, electrons spin in different, random directions. This causes them to cancel each other out over time. However, magnets are different. BBC Bitesize - KS2 Science - What is rust?
