JEE Main 2019 — Electromagnetic Induction Question with Solution
From: JEE Main 2019 (Online) 12th April Morning Slot
Question
The figure shows a square loop L of side 5 cm which is connected to a network of resistances. The whole setup is moving towards right with a constant speed of 1 cm s-1. At some instant, a part of L is in a uniform
magnetic field of 1 T, perpendicular to the plane of the loop. If the resistance of L is 1.7 , the current in the
loop at that instant will be close to :
