About This Lesson
Ever wonder how a compass worked to point you to the Arctic? Explore the interactions between a compass and bar magnet, and then add the earth and find the surprising answer! Vary the magnet's strength, and see how things change both inside and outside. Use the field meter to measure how the magnetic field changes;
Sample Learning Goals
•Predict the direction of the magnet field for different locations around a bar magnet
•Relate magnetic field strength to distance quantitatively and qualitatively
•Describe how the earth's magnet field relates to a bar magnet
