Linear Motional EMF

JEE Main asked Linear Motional EMF 7 times in 6 of the 108 shifts Lumi analysed, in 2021, 2022 and 2023. It belongs to Faraday's Law, in Electromagnetic Induction (Physics). The longest wait between two years asking it was 1 year. In 2021 and 2023 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
