A coil that is circular has a radius of 8 cm and has 400 turns it is on a table horizontally. A magnetic field that is uniform is pointing exactly up is turned on slowly, the strength of the magnetic field is expressed as a function of time as: B(t) = 0.04(T /s2) × t2. What is the total EMF in the coil as a function of time and in which direction does the current flow?
