MagLev Trains

MagLev Trains

• Every magnet has two poles, a north pole and a
  south pole.
• Like poles push the magnets away. They are
  repulsive.
• Opposite poles pull the magnets together. They
  are attractive.

• What happens when you put two magnets on a
  pencil? How do you get the top one to float?
• This is how MagLev trains work. They use magnets
  to make the train float so that the friction is
  very small.

Levitation Chamber!

• What other cool things can we do with magnetism?
• We can make a levitation chamber out of a
  Pringles can and make a paperclip float, like in
  the picture.
• How is the paperclip floating?

• The gravitational force pulls the paperclip down.
• The force between the magnet and the paperclip
  pulls the paperclip up.
• If the magnet is strong enough, the magnetic
  force will overpower gravity and pull the
  paperclip up!
• The string keeps the paperclip from going all the
  way to the magnet.
