I'm having a lot of difficulty understanding the "skin effect" in physics.

Would you be able to explain it to me? I believe a diagram would help me a lot, but youtube and teacher tube did not have any relevant animations. I don't really understand those provided by Google images.

If this helps:

The skin effect is the uneven distribution of current carriers throughout the cross-section of a conductor when it is carrying an alternating current. The current density becomes greater at the surface than it is at the centre. The skin effect is caused by electromagnetic effects, and it becomes more significant as the frequency of the alternating current increases. One consequence of the skin effect is that the effective resistance of a conductor is greater when it is carrying an alternating current when compared with its true or direct current resistance.
