About this Simulation

This interactive simulation allows learners to explore the magnetic fields produced by two bar magnets and observe how a compass needle responds. Students can adjust magnet positions and orientations to visualize field lines, study dipole interactions, and understand how Earth's magnetic field influences compass behavior in real-time.

Learning objectives: Understand how magnetic field patterns form around bar magnets and change with configuration | Observe how compass needles align with magnetic field directions | Analyze the superposition of magnetic fields from multiple sources and Earth's magnetic influence
