Magnetism
By: Aleina, Payton, and Kaitlyn
Properties of Magnets
1. Attract iron/materials with iron
2. Attract or repel other magnets
3. Point north when they swing freely
Magnetic Fields
What are they?
A region around a magnetic material or a moving electric charge within which the force of magnetism acts.
A picture is in the diagram below.
How is distance determined?
The distance between magnetic fields indicates the strength of a magnetic field.
Where are field lines the strongest?
As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.

Repelling
Here is a diagram that shows the repelling of a magnet.
Repelling occurs when the same poles get pushed together.
Attract
This diagram shows the attraction of magnets.
Attraction occurs when the opposite poles get pushed together.
