🎬how the difference in how an electric field propagates through a vacuum versus how it propagates thr

Vacuum (Free Space) allows an electric field to propagate unimpeded and equally in all directions. This property is correctly described by the identity tensor (scaled by the constant ε₀), which maintains the field's direction and strength. A zero tensor would imply that no electric field could exist or travel through a vacuum. In contrast, Dielectric Material actively opposes the electric field. As the demo shows, the material's dipoles align to create an internal field that reduces the net strength of the external field passing through it.
