Magnetism
Kyle E. and Arnel T.
Properties of Magnets
- attract iron or materials that contain iron
- attract or repel other magnets
- point north when they swing freely
Magnetic Poles
2 types of poles-
- north
- south
Interacting poles-
- like poles repel
- unlike poles attract
Interacting poles
Magnetic Force
2 types of force-
- push
- pull
The relationship between magnetic force and poles-
Magnetic force either repels or attracts magnets.
Magnetic Fields
1. A magnetic field is the area of magnetic force around a magnet
2. How is distance determined?
It's based on the strength of the magnetic force- strong force= closer together and weak force= farther apart.
3. Strength of field lines-
- closer to the poles= stronger
- farther from the poles= weaker
Magnetic Domains
1. This is a photo of magnetic domains in a magnetic material and a non- magnetic material-------------------------------------------------------------->
2. Magnetism is affected by magnetic domains-
If all of the domains are pointing in the same direction the material is magnetized, if they are all pointing in random directions the material is not magnetized.
