This simulation models the magnetic field surrounding a bar magnet and demonstrates how compass needles respond to magnetic forces. Learners can visualize field lines, adjust magnet orientation, and observe how the magnetic field strength varies with distance and position relative to the magnet.
Learning objectives: Understand how magnetic field lines represent field strength and direction around a bar magnet | Predict compass needle alignment based on magnetic field orientation | Explore the relationship between dipole strength and observable magnetic effects
