Induced field in a conductor

  1. Jan 24, 2010 #1
    According to "Introduction to Electrodynamics" - Griffiths

    I have a few questions about the bolded section

    Say for instance you apply an external field of 1,000,000,000 N/C. The conductor only has a limited number of electrons to spare, so the only way you could possibly create a great enough opposing field would be to have all the electrons very close to the protons, but in that case they might not be at the surface of the conductor.

    What if you applied a field of 0.00000001 N/C, and all the electrons went to one side. How can it be proven that enough electrons will be persuaded to move to that side to cancel out even this miniscule field?

    Thanks
