Vedclass · Answer

(A) According to Faraday's law of electromagnetic induction, an induced electromotive force $(EMF)$ and current are produced only when there is a change in the magnetic flux $(\Phi_B)$ linked with a circuit over time.Magnetic flux is defined as $\Phi_B = \int \vec{B} \cdot d\vec{A}$.In this scenario, the cylinder is placed parallel to a uniform magnetic field $\vec{B}$. Since the magnetic field is uniform and the cylinder is stationary, the magnetic flux passing through any cross-section of the cylinder remains constant over time.Since $\frac{d\Phi_B}{dt} = 0$, there is no induced $EMF$ and consequently no induced current.Therefore, the induced current is zero.

An infinitely long cylinder is kept parallel to a uniform magnetic field $B$ directed along the positive $z$-axis. The direction of induced current as seen from the $z$-axis will be
