A circular coil of radius 5 cm has 50 turns of wire. The uniform magnetic field...

A circular coil of radius 5 cm has 50 turns of wire. The uniform magnetic field directed into the page/screen (see the figure below) is linearly increased in magnitude form 0 to 0.8 T. What time interval for this increase is needed to induce in the coil emf = 0.25 V? What is the direction of the induced emf (clockwise/counterclockwise)? Which law do we use?
