Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers! • 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 the conditions that produce induction. • Compare and contrast how the light bulb and voltmeter show characteristics of the induced current. • Predict how the induced current will change when the experimental conditions are varied.
