A flat square coil with $245$ turns, each one of side $48$ cm $,$ is oriented with its plane perpendicular to a uniform magnetic field. The field varies at constant rate from $0\mathrm{.}00$ T to $2\mathrm{.}6$ T in $45$ ms $.$ Calculate the induced emf and the induced current in the coil during this time if the resistance of the coil is $82.$

Instead of varying the magnetic field, its direction is fliped in time $11$ ms while keeping its constant magnitude $2\mathrm{.}4$ T$.$ Calculate the induced emf and the induced current in the coil during this time if the resistance of the coil is $52.$
