Exact Electromagnetic Fields Produced by a Finite Wire with Constant Current
Jimenez, J. L.; Campos, I.; Aquino, N.
European Journal of Physics, v29 n1 p163-175 Jan 2008
We solve exactly the problem of calculating the electromagnetic fields produced by a finite wire with a constant current, by using two methods: retarded potentials and Jefimenko's formalism. One result in this particular case is that the usual Biot-Savart law of magnetostatics gives the correct magnetic field of the problem. We also show graphically the corresponding Poynting vector. (Contains 7 figures.)
