A wire bent as a parabola `y=ax^(2)` is located in a uniformed magnetic field of induaction `B` , the vector `B` being perpendicular to the plane `x-y` . At moment `t=0` a connector starts sliding translationwise from the parabola apex with a constant acceleration `omega` . Find the emf of electromagnetic induction in the loop thus formed as a function of `y`
