JEE Main 2021 — Electromagnetic Induction Question with Solution
From: JEE Main 2021 (Online) 27th August Evening Shift
Question
A constant magnetic field of 1T is applied in the x > 0 region. A metallic circular ring of radius 1m is moving with a constant velocity of 1 m/s along the x-axis. At t = 0s, the centre of O of the ring is at x = 1m. What will be the value of the induced emf in the ring at t = 1s? (Assume the velocity of the ring does not change.)
This question includes a diagram. The text above accompanies the figure.

Correct answer
C2V
Step-by-step explanation
emf = BLV
= 1 . (2R) . 1
= 2V
= 1 . (2R) . 1
= 2V
