Negative charges create negative electric potentials at points in space around them, just like positive charges create positive electric potential values at points in space around them. The Higgs Field: The Force Behind The Standard Model, Why Has The Magnetic Field Changed Over Time. 0 The first step to solving for the magnitude of the electric field is to convert the distance from the charge to meters: r = 1.000 mm.
