🎬Contrasting Static Field Energy Densities-Decay vs. Uniform Confinement

The visualization effectively demonstrates the fundamental differences in static field energy distributions for two canonical systems. For the electrostatic case of a point charge, the energy density ( $u_E$ ) is shown to follow a steep inverse fourth power law ( $u_E \propto 1 / r^4$ ), illustrating that the vast majority of the field energy is critically concentrated in the immediate vicinity of the source charge. In contrast, the magneto-static demo simulating an ideal solenoid shows that its energy density ( $u_B$ ) is uniform and constant within the field's confinement region, emphasizing that magnetic field energy, when contained within devices like solenoids, is perfectly localized within a specific, well-defined volume.
