Magnetism
Magnetism is a natural invisible force that attracts certain object.
It's like a static energy that forces electric currents to move. Some
scientist noticed that a rock can be a magnet, but most people know that
magnets work because of the electric charges.
What is a magnet?
A magnet is a piece of iron or steel that attracts certain objects. Like
metals, a magnet is made up of small particles called molecules, which
in turn are made up of atoms. All the molecules in a piece of iron are
facing different directions. If the molecules are rearrange to make them
face the same way, they will act together as a magnet that creates a
powerful force.
Make it work
You may try to test the power of magnet through a simple experiment.
Just follow the instructions below.
You will need
- a small magnet with a hole in the center
- thin cardboard
- paint
- brushes
- black marker
- thin wire mesh
- dowel and string
- X-Acto knife
- paper clips
- stencil brush
Procedure:
- Cut out large, medium, and small fish shapes from different colors of
cardboard.
- Draw in the eye, gills, and mouth with a black marker.
- Create a fishing line by tying the magnet to the string. Attach the
