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

A big circular coil of $1000\text{turns}$ and average radius $10\text{m}$ is rotating about its horizontal diameter at $2\text{rad/s}$. If the vertical component of earth’s magnetic field at that place is $2\times 10^{-5}\text{T}$ and electrical resistance of the coil is $12.56\Omega$, then the maximum induced current in the coil will be:
