About this Simulation

This simulation lets you visualize magnetic field lines in three dimensions around a bar magnet. Explore how field strength varies with distance, rotate the view to understand field geometry, and manipulate arrow density and scale to reveal magnetic field patterns. Ideal for understanding dipole fields and field line behavior.

Learning objectives: Visualize and interpret 3D magnetic field line patterns around a bar magnet | Understand how magnetic field strength and direction vary in space | Explore the relationship between field line density and magnetic field intensity
