Magnetic Levitation Device

Science Exhibition Models

Things you will need:

  • Two bar magnets: North and South Pole should be labeled.
  • Two Ring Magnets
  • A sketch pen
  • Pencil
  • Modeling Clay to hold the pencil
  • Notebook

How to do it:

  • Take the two bar magnets and place them on the table. You will notice that the bar magnets have north and south Pole labeled on them. Bring the two similar poles near each other, for instance, the north-north sides. Create a table and keep a record of how the poles interact with each other.
  • The data table that you created will help you in concluding how the sides interact.
  • By now you would have clear idea as to how the poles interact with each other when one brings them close. Make use of that data to find out the ring magnets north and south pole.
  • Bring one flat side of the ring magnet nearer to the north pole of the bar magnet. Does the ring magnet attract or repel the bar? Based on how the side reacts to the labeled bar magnet mark the side.
  • This process will be repeated until both the sides are labeled.
  • When the poles are labeled we will be ready to create the conditions under which the levitation can take place.
  • Firstly, the ring magnet needs a holder. To create that we will take the modeling clay and stick the pencil into it vertically. Make sure the pointy end is downwards.
  • Take this setup and put one of the ring magnets into the pencil. It will slip down to the base. Remember the North Pole should face up.
  • Slip the second magnet into the pencil with the north pole facing the north pole of the ring magnet underneath. Voila! You will see that the second magnet will start floating.
  • Remove the pencil carefully and now you have a levitating magnet.

What’s going on?

Magnets have a property that their unlike poles react and like poles repel. The alignment of two magnets depends on whether they attract or repel. This project makes us discover how the two magnets create a repelling force between them. Later, we used that same information to create our own magnetic levitation device.
