Question

Why don't electric fields exist inside of conductors??

Answer 1

They don't exist only when all motion has ceased (electrostatic case). The quick answer is that motion will only cease when all forces are balanced out, and that can't happen if there is an electric field since F = qE. In the electrostatic case, all excess charges are on the surface of the conductor, so Gauss would say that since there is no net charge in a closed surface within the conductor, there can be no net flux, and thus no net electric field.

Answer 2

electric field(E) is related to flux as E=flux/area.Gauss law states that flux enclosed in a closed surface is q\E0.for a conductor charges reside on the surface not inside the conductor because of presence of free electrons which align in the direction of electric field when subjected to it.so no charge=no flux=no electric field

Answer 3

Free electrons alligh themselves such that there will be no further movement of charge within the conductor in case of static electricity. As a result net E within conductor becomes zero.

Answer 4

What does align mean? They don't align, they move... in the direction opposite to the electric field. the field doesn't disappear because there is no further movement, there is no further movement because the field is cancelled out. Sounds like confusing cause and effect.
