Skin Effect in Electromagnetism: Detailed Explanation

Click For Summary
SUMMARY

The skin effect in electromagnetism describes the phenomenon where alternating current (AC) tends to flow near the surface of a conductor rather than uniformly throughout its volume. This effect occurs due to the self-induction of the current, which creates an opposing electromagnetic field that increases with depth, leading to a higher current density at the surface. The discussion highlights the need for a deeper understanding of the underlying physics, particularly the behavior of electrons in response to induced electromotive forces within the conductor.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with alternating current (AC) principles
  • Knowledge of self-induction and electromagnetic fields

I read the wikipedia link, and it does not explain as to why the current density is maximum at the surface and as to why the induced electro-motive force is maximum at the centre?
And more so why do the electrons get deflected the most towards the surface from the centre??
