About this Simulation

This interactive simulator models the invisible magnetic field surrounding a bar magnet. Students can visualise field line patterns, adjust magnet dimensions and field range, control line density and stroke width, and observe how these parameters affect the field representation in real time.

Learning objectives: Understand how magnetic field lines represent the direction and strength of magnetic forces | Explore the relationship between magnet size, field range, and field line density | Develop spatial reasoning by manipulating and observing field visualisation parameters
