A square loop of wire $($edge length $48$ cm$)$ is found to have an induced emf of $1\mathrm{.}5$ V at

t $=0.$

$($a$)$ Assuming the magnetic field is perpendicular to the loop and that the magnitude of the field varies linearly with time, what is the change in the magnetic field from

t $=0$ to t $=0\mathrm{.}11$ s$?$
