JEE Main 2020 — Electromagnetic Induction Question with Solution
JEE Main 2020 (07 Jan Shift 1)
Question
Consider a circular coil of wire carrying constant current 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 The magnetic flux through the area of the circular coil area is given by . Which of the following option is correct?

Correct answer
D
Step-by-step explanation
As magnetic field lines always form a closed loop, hence every magnetic field line creating magnetic flux in the inner region must be passing through the outer region. Since flux in two regions are in opposite direction.
