The electric field outside a stationary resistive wire carrying a constantcurrent

We present the opinion of some authors who believe there is no force betwee n a stationary charge and a stationary resistive wire carrying a constant c urrent. We show that this force is different from zero and present its main components: rile force due to the charges induced in the wire by the test charge and a force proportional to the current in the resistive wire. We al so discuss briefly a component of the force proportional to the square of t he current which should exist according to some models and another componen t due to the acceleration of the conduction electrons in a curved wire carr ying a dc current (centripetal acceleration). Finally, Ive analyze experime nts showing the existence of the electric field proportional to the current in resistance wires.
