Kate's Corner: Experimenting with magnets

By  | 

BRIDGEPORT, W. Va. (WDTV) - We recently had our science lesson on magnets and how they work.
Now it is time to use that knowledge in an experiment.

In this experiment, we will be using different liquids and seeing how they affect the magnet's magnetic field.

We have three different liquids: water, vegetable oil, and corn syrup. Drop a few paper clips into each cup and now we will test our magnet.

Put the magnet up to the side of each glass and see how fast the paper clips move.

As you will see, the paper clips moved the fastest in the water and the slowest in the corn syrup.

Why do the paper clips move at different speeds?

That is all because of the consistency of each liquid. The thickness or viscosity affects the magnetic attraction. Since the corn syrup is thicker, there is more resistance between the paper clip and magnet.
