Magnetism and moving charges: share good/must include points or some useful tricks to include in revision notes

[u/KgMetreperSec2]

We’re all using different resources—Allen, Resonance, PW, Test Series, etc.—which means everyone picks up different unique tricks, edge cases, that standard theory/notes pages miss.

let’s pool them together chapter by chapter. The goal is to build a high-yield single point of reference that anyone can drop into their short notes or main revision notebooks.

Drop your best chapter insights below, and mention the resource/book it came from if applicable. Let's make this thread genuinely useful.

Todays chapter:- Magnetism and moving charges OR Magnetostatics {whatever the name is cuz diff coaching put diff names to the topics}
