Summary
| Description |
English: Diagram of electric charges induced in conductive objects (shapes) by the electrostatic field (lines with arrows) of a nearby charge (+), due to electrostatic induction. An electric charge near a metal object causes the mobile charges in the metal to separate. If the external charge is positive as shown, negative charges (blue) are attracted and move to the surface of the object facing the external charge, positive charges (red) are repelled and move to the surface of the object facing away. This charge separation quickly reaches an equilibrium and stops when the induced surface charges are exactly the right size and shape so their opposing electric field cancels the external electric field throughout the interior of the metal. Therefore electrostatic field lines cannot penetrate conductive objects; they always end on induced charges on the surface, and the interior of a conductive object is at a constant electrostatic potential. The drawing also illustrates that electric field lines at a metal surface are always normal (perpendicular) to the surface except at sharp corners, and induced charge tends to collect at sharp edges and pointsThis is a computed drawing and the distribution of the electostatic field lines and charges shown is quantitatively accurate. |
