Question 95: Electromagnetic Induction

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 $$\phi $$
i
. The magnetic flux through the area of the circular coil area is given by $$\phi $$
0
. Which of the following option is correct?

Accepted Answer

As, magnetic field lines forms a closed loop, hence each line from circular area will pass through outer area
in opposite direction hence $$\phi $$
i
= - $$\phi $$
0
.

Answer

$$\phi $$
i
= $$\phi $$
0

Answer

$$\phi $$

< $$\phi $$
0

Answer

$$\phi $$
i
$$>$$ $$\phi $$
0

Answer
