學習目標

• Predict the direction of the magnetic field for different locations around a bar magnet and an electromagnet.
• 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.
• Relate magnetic field strength to distance quantitatively and qualitatively.
• Identify equipment and conditions that produce induction.
• Compare and contrast how both a light bulb and voltmeter can be used to show characteristics of the induced current.
• Predict how the current will change when the conditions are varied.
