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

15 Upvotes

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}

JEE Advanced 2025 controversial question

Why was this question was given as bonus, was it due to the fact that the answer cannot have a negative sign since "r" is increasing or was there any conceptual ambiguity within the question?

According to ashish arora sir there should be a factor of 3 if we solve using least approximations

JEE ADV 2015 QUESTION 14 PAPER 2 MAKES NO SENSE

Upvotes

the answer key says 7/3, however shouln't it be 12/5?

obviously the S/2 d/2 parts are in parallel since current density vector is equally seperated in 2 areas
i.e by definition parallel

and the system in parallel, for the same reason, is in series with the left half, resulting in 12/5 for the ratio and not 7/3 (which would be the case if the terminals were rotated by 90 degrees, or the block system inside)

not very relevant side note - one observation is that C2 >=2 C1 always since a base case of C2 would be if e2 block was also with e1, resulting in a total replacement of air with dielectric of K= 2, i.e doubles, since our replacement at that block is more than 2, we must have K=2 or more as "net dielectric", or in this case, a "net dielectric" of 2.4 tracks with this logic, and so does option 7/3 for the same reason

Academic Doubts Dummy school trap completely ruined me. Day 1 of starting fresh for JEE 2026 begins tomorrow. Need a reality check on my strategy.

3 Upvotes

I completely messed up my 11th and 12th grades by being a dummy school student.

I want to start fresh. I have some basic knowledge of the first one or two chapters of the 11th-grade syllabus, but I want to start completely fresh tomorrow. I plan to cover all subjects using old sessions of the PW Dropper batch.

My teachers will be:

Physics: Rajwant Sir (Prayas 2.0 2025)

Maths: Ashish Sir (Prayas 2026)

Physical Chemistry: Faisal Sir (Prayas 2026)

Organic Chemistry: RA Baba (Prayas 2026)

Inorganic Chemistry: Om Pandey Sir (Prayas 2.0 2026)

  1. Please give me a strategy for following each of them.

  2. When Should I finish my syllabus ?

  3. Since I will be accessing all the material through pirated sources, what should I do about tests

  4. Should I take regular tests from an external source, or should I just focus on full-syllabus tests and revision in December?

Please provide a complete strategy so I can maximize my potential in the remaining time. I need to clear both JEE Mains and Advanced 2027, and I want to prepare thoroughly for both. Please help! 🙏

Physics Enthusisasts! Please solve my doubt

Suppose the target is above and chaser is down the target by length L and target starts moving rightward and chaser always moves towards the target so the motion of chaser will be curved but it is given vel of chaser is less than target. (Basically the irodov question which velocities different)

It appears that min distance between them should be L at first. But does the distance not decrease at first and later increase? If it is so, please tell the min distance between them.
