Key findings
- 01
Asked in 8 of 8 years with analysed shifts and in 16 of 108 shifts: 16 questions, #153 of 196 topics. It came in every year with analysed shifts.
- 02
53% of its questions since 2020 tested an idea no earlier year had asked; 2 repeated an idea from the year before.
- 03
The most repeated idea is Torque in Uniform Field, asked 4 times in 4 shifts (2017, 2022, 2023, 2025), most often as “torque on dipole between capacitor plates”.
- 04
JEE Main has asked 9 of the 56 ideas in this topic; 45 have never been asked, directly or inside another question.
- 05
Mostly asked as single correct (69%); 19% need a numerical answer, 31% are easy and 19% hard.
- 06
The skill tested most is multi-step (44%), then calculation (25%).
Questions a shift, year by year
Out of the 25 Physics questions in a shift. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift.
Raw count: 2017: 1 in 1 shift · 2020: 2 in 12 shifts · 2021: 2 in 24 shifts · 2022: 1 in 24 shifts · 2023: 5 in 12 shifts · 2024: 2 in 18 shifts · 2025: 1 in 8 shifts · 2026: 2 in 9 shifts.

New idea, or one asked before?
Each column is a year. Blue questions tested an idea no earlier year had asked; navy ones went back to an idea from an earlier year. 2017 is the first year, so everything in it counts as new. Heights are question counts, and Lumi analysed 1 to 24 shifts a year, so compare the split inside a column rather than heights across years.
- Idea asked for the first time
- Idea asked in an earlier year
Coverage of the topic
JEE Main has asked 9 of the 56 ideas in this topic. 45 have never been asked yet.
- Asked directly9 · 16%
- Touched inside another question2 · 4%
- Never asked45 · 80%
Ideas come from Lumi’s JEE syllabus map. A never-asked idea is not a safe skip: across all of JEE Main, 22% of questions since 2024 tested an idea no earlier year had asked.

Squares are the 8 years with analysed shifts, 2017 to 2026. A number is the questions that year when there is more than one; the shade is scaled to one shift, so a year with more analysed shifts (1 to 24 a year) does not look darker. Share is of the level above.
