"WebThe permittivity of free space is a number which allows us to describe how easily (or how difficult) it is for electric lines of force to pass through air, water or any other medium. It's called permittivity because of how much a given substance "permits" electric, (or magnetic in the case of magnetism ) field lines to pass through them. " - Permittivity in physics
