Best Answer

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.

What is an edge effect?

My guess is you're referring to the edge effect on electric fields. In many textbooks, and many problems dealing with electric fields you will see assumptions used to minimize the effect an edge has on the electric field you're attempting to analyze, which is done to simplify the problem. One common example is determining the electric field strength at a point a given distance from a conductor carrying X amount of current. It's often assumed that this is an infinitely long conductor. This removes the need to analyze the electric field due to the corner of the conductor, where the shape, sharpness of the corner, size, type of conductor, and amount of current can impact the actual effect that corner has on the electric field strength at a given distance from the conductor. Usually the impact of the corner is minor, so it can be ignored by assuming an infinite conductor. Other examples: -calculating the electric field X distance from a charged plate (assume the plate is infinite)


What is fringing electric field?

Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.


What is edge effect?

edge effect is the different conditions along the boundries of an ecosystem.


What is fringing effect?

Apparent boost in lows because of full track being played on multitrack machines. If you have two parallel plates forming a capacitor, the electric field does not end abruptly at the edge of the plates. There is some field outside that plates that curves from one to the other. This causes the real capacitance to be larger than what you'd calculate using the ideal formula. You have more electric field because of the fringe fields.
