Question

A square loop of side $1	ext{ m}$ and resistance $1	ext{ }\Omega$ is placed in a magnetic field of $0.5	ext{ T}$. If the plane of loop is perpendicular to the direction of magnetic field, the magnetic flux through the loop is

Accepted Answer

Magnetic flux $\phi_B = \vec{B} \cdot \vec{A}$. Since $\vec{B}$ and $\vec{A}$ are in the same direction, $\phi_B = B \cdot A = 0.5 	imes (1)^2 = 0.5	ext{ Wb}$.
