Main Question or Discussion Point

I can't find sth about self interaction which tells for sure in what situations we should consider it and how to manipulate it!
Can we talk about self interaction for e.g. a single electric charge?Or it appears only in certain cases?How should we calculate it?

Thanks

Well there is a distinction between mutual inductance and self inductance.
Is this the sort of idea you mean?
What is 'sth' by the way?

self interaction as in QED and Feynman sums?
Look up "renormalization".

A single electron can have a self interaction, yes.

No,I didn't mean inductance!
I mean the effect of a charge's field on the charge itself.
And of course «something» means a webpage,paper,etc which talks about self interaction!!!!!!
Thanks for caring anyway
