What impact does edge effect have on electric fields?

Answer 1

The magnitude of the electric field gets very big nearby sharp edges of the charged object. This leads to molecules in the surronding air being ionized, decharging the object at the same time as it leads to the ionized molecules repelling the object, creating a stream of ions away from the edge.

Answer 2

Edge effect can cause distortion and interference in electric fields near sharp edges or boundaries of conducting materials, leading to non-uniform electric field distribution. This can affect the accuracy and efficiency of electrical devices, especially in high-frequency applications where edge effects are more pronounced. Proper design techniques, like adding shielding or rounding edges, can help minimize these effects.
