A planar coil of wire has a single turn. The normal to this coil is parallel to a uniform and constant (in time) magnetic field of 1.80 T. An emf that has a magnitude of 2.40 V is induced in this coil because the coil's area A is shrinking. What is the magnitude of AA/At, which is the rate (in m²/s) at which the area changes?
