Magnets and Electromagnets explore the interactions between a compass and bar magnet. Discover how you can use a battery and wire to make a magnet. Can you make it a stronger magnet? Can you make the magnetic field reverse? Study magnets and electromagnets.

Sample Learning Goals
1. Predict the direction of the magnet field for different locations around a bar magnet and electromagnet
2. Compare and contrast bar magnets and electromagnets
3. Identify the characteristics of electromagnets that are variable and what effects each variable has on the magnetic field's strength and direction
4. Relate magnetic field strength to distance quantitatively and qualitatively
