A magnetic field is uniform in distribution across a region of space but the strength on the field varies time according to the formula B= 1.5 t^2 where the units have been left off but t is in seconds and is in Tesla. If this field passes straight through a flat wire loop enclosing an area of 0.60 m^2 what the emf induced in this wire loop, at a time of 3 seconds?
