Abstract
Contrary to what is sometimes assumed, it is mathematically impossible to w rite down a magnetic field of a current system that is not closed. When the Biot-Savart law is integrated over a current that ostensibly is not closed , the resulting magnetic field is that of a system containing a closure cur rent which is uniquely determined but may neither be physically realistic n or correspond to the desired approximation.
