Key findings
- 01
Asked in 6 of 10 papers, 8 questions in all: #106 of 204 topics by ten-year total. It comes back every 1.8 years on average.
- 02
71% of its questions since 2018 tested an idea never asked before; none repeated an idea from the year before.
- 03
The most repeated idea is B vs r Graph for Solid Cylinder, asked 2 times (2019, 2022), usually as “field variation inside and outside current-carrying wire”.
- 04
NEET has asked 6 of the 85 ideas in this topic; 72 have never been asked, directly or indirectly.

Repeats
New idea, or one asked before?
Each column is a paper. Blue questions tested an idea NEET had not asked before; navy ones went back to an idea from an earlier paper. 2017 is the first paper, so everything in it counts as new.
- Idea asked for the first time
- Idea asked in an earlier paper
Coverage of the topic
NEET has asked 6 of the 85 ideas in this topic. 72 have never been asked yet.
