358471 A square, a circular and an elliptical loop, all are in the \((x - y)\) plane, are moving out of a uniform magnetic field with a constant velocity \(\vec{v}=\hat{i}\). The magnetic field is directed along the negative \(z\) axis direction. The induced emf, during the passage of these loops, out of the field region, will remain constant for
