|Title:||The electric field outside a stationary resistive wire carrying a constant current|
|Abstract:||We present the opinion of some authors who believe there is no force between a stationary charge and a stationary resistive wire carrying a constant current. 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 also discuss briefly a component of the force proportional to the square of the current which should exist according to some models and another component due to the acceleration of the conduction electrons in a curved wire carrying a dc current (centripetal acceleration). Finally, Ive analyze experiments showing the existence of the electric field proportional to the current in resistance wires.|
