Can you find the magnetic north pole by the help of an apple or a tennis ball? In this easy experiment we will show you how you can do it.
Thing Required:
Apple or tennis ball
Directions:
Hold the apple in your right hand, and assume it is the earth, spinning on its axis. Wrap your fingers around the sides of the apple, with your thumb sticking up.
This Is What Happens:
Your fingers point in the same direction as the earth spins. Your thumb points in the same direction as does the earth’s magnetic north pole.
Science Behind It:
The entire earth, including the liquid core, spins in a counterclockwise direction. Electrons are rubbed from this turning liquid, but they continue to move in the same direction as the earth. A magnetic field is always present around moving electrons. The direction of the magnetic field can always be determined by using your right hand. Point your fingers in the direction of the moving electrons, and your right thumb will indicate the direction of the magnetic north pole.
