JEE Main 2020 — Electromagnetic Induction Question with Solution
From: JEE Main 2020 (Online) 3rd September Evening Slot
Question
A uniform magnetic field B exists in a direction perpendicular to the plane of a square loop made of
a metal wire. The wire has a diameter of 4 mm and a total length of 30 cm. The magnetic field
changes with time at a steady rate = 0.032 Ts–1. The induced current in the loop is close to
(Resistivity of the metal wire is 1.23 10–8 m)
