Sample Learning Goals

• Predict the direction of the magnetic field for different locations around a bar magnet and an electromagnet.
• Relate magnetic field strength to distance quantitatively and qualitatively.
• Describe how the earth’s magnetic field relates to a bar magnet.
• Compare and contrast bar magnets and electromagnets.
• Identify the characteristics of electromagnets that are variable and what effects each variable has on the magnetic field’s strength and direction.
