# Wire in changing B field

pythagoras88
Does a straight wire in changing B field(the field is perpendicular to the wire) has an induced emf?

E=-s/2. dB/dt.$$\phi\widehat{}$$. Assuming the B field is uniform throughout the plane, and is changing at constant rate. So, if the square loop is put at a distance from the center of the field, then the induced E field in it seems to be different as E has the dependence on s. Thus, result in a seemingly difference emf induced if the loop is placed at different region.
However, from faraday's law, $$\epsilon$$=-d$$\Phi$$/dt. Since the area enclosed by the loop is the same plus the rate of change of B field is the same, it implies that the emf induced is the same in the loop no matter where it is placed in the B field.
