Magnetic Fields
We begin our discussion of magnetic fields by a discussion of what is meant by a north pole or a south pole of a magnet, and how the poles interact with each other when they are near each other. Although magnetic effects resemble the electric effects we discussed in the previous unit, there are also differences. A compass or iron filings can be used to determine what the magnetic field lines for a magnet or combination of magnets looks like. Once we know what the magnetic field line pattern is, we can use vectors to draw the relative strength and direction of a magnetic field vector at any point, much as we did in our study of electric fields. We will conclude the lesson by drawing magnetic fields for combinations of magnets placed near each other.
Think back to the magnetic experiments we did yesterday. Read through the following document making notes on:
Explain how magnetic poles work.
What is a magnetic field?
What is meant by magnetic monopole.
What will the magnetic field lines look like around a bar magnet? a horseshoe magnet? 2 bar magnets with like poles together? 2 bar magnets with unlike poles together?
