Creative tip: hover over the heatmap to inspect local Bz and correlate it with the axis curve.

What You Learn

This lab helps you connect moving charges to macroscopic current-loop magnetic fields. You can see how the z-component of magnetic field is distributed in the coil plane, and compare the simulated on-axis field with the analytical Biot-Savart result. It builds intuition for discretization effects, symmetry, and how field magnitude changes with radius, angular speed, and charge count.
