Faraday's Law: NEET previous year questions

12 questions in ten years of NEET, in 8 of 10 papers. Pattern: Every year. Here is how it is asked and which ideas come back.

Asked in 10 years: 12; about 1.2 per paper
Years asked: 8/10; last asked 2026
Chance of a question next paper: 84%; historical rate, how we compute it
Weighted estimate: 1.4; model; history: 1.2 a paper on average, typically 0–2

Key findings

01
Asked in 8 of 10 papers, 12 questions in all: #54 of 204 topics by ten-year total. It comes back every 1.3 years on average.
02
82% 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 Self Inductance, asked 3 times (2018, 2023, 2025), usually as “numerical”.
04
NEET has asked 10 of the 95 ideas in this topic; 82 have never been asked, directly or indirectly.
05
Mostly asked as numerical (50%); 42% easy, 8% hard.

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.
