JEE Main 2021 — Electromagnetic Induction Question with Solution
From: JEE Main 2021 (Online) 27th August Morning Shift
Question
A bar magnet is passing through a conducting loop of radius R with velocity . The radius of the bar magnet is such that it just passes through the loop. The induced e.m.f. in the loop can be represented by the approximate curve :

Correct answer
C
Step-by-step explanation
When magnet passes through centre region of solenoid, no current / Emf is induced in loop.
While entering flux increases so negative induced emf
While leaving flux decreases so positive induced emf.
