A circular turn of radius $1$ m revolves at $60$ rpm about its diameter aligned with the xaxis as shown in the figure. The value of $\mu_{0}$ is $4\pi \times 10^{7}$ in SI unit. If a uniform magnetic field intensity $\vec{H}=10^{7}\hat{z}$ A/m is applied, then the peak value of the induced voltage, $V_{turn}$ ( in Volts), is _________.

In cylindrical coordinate system, the potential produced by a uniform ring charge is given by $\phi = f(r, z)$ where $f$ is a continuous function of $r$ and $z$. Let $\vec{E}$ be the resulting electric field. Then the magnitude of $\nabla \times \vec{E}$ Increases with $r$ Is $0$. Is $3$. Decreases with $z$.
