The permittivity
WebbThe permeability of free space, μ0, is a physical constant used often in electromagnetism. It is defined to have the exact value of 4π x 10 -7 N/A 2 ( newtons per ampere squared). … Webb6 maj 2024 · The permittivity of a medium describes how much electric field (more correctly, flux) is “generated” per unit charge in that medium. More electric flux exists in a medium with a high permittivity (per unit charge) because of polarization effects.
