JEE Main 2020 — Electromagnetic Induction Question with Solution
From: JEE Main 2020 (Online) 7th January Morning Slot
Question
Consider a circular coil of wire carrying constant current I, forming a magnetic dipole. The magnetic flux through an infinite plane that contains the circular coil and excluding the circular coil area is given by i. The magnetic flux through the area of the circular coil area is given by 0. Which of the following option is correct?

Correct answer
Di = - 0
Step-by-step explanation
As, magnetic field lines forms a closed loop, hence each line from circular area will pass through outer area
in opposite direction hence i = - 0.
