A $20-cm$ side length square coil has $215$ turns. An initial uniform magnetic field of strength $9\mathrm{.}5$ mT is applied perpendicularly to the plane of the coil. Calculate the magnetic flux through the coil.

The flux, $=$ Units $$ Select an answer $.$

If the field increases in strength from the initial value to $14\mathrm{.}5$ mT in $0\mathrm{.}25$ s $,$ what average emf is induced in the coil?

The induced emf, emf $=$ Units $.$

What is the average current in the coil if it's resistance is $180?$

The current, I $=$ Units Select an answer $$
