A solenoid is formed by wrapping the wire around a tube with the windings closely spaced. Applying the Biot-Savart law to this helical wire reveals that for a long, tightly wound solenoid, the field is very strong and very uniform inside the tube, and very weak outside the tube.
However, a limitation of Biot– Savart's law is that it is applicable only to free space; that is, magnetic fields near the ferromagnetic material in the vicinity of the end winding have significant errors between the measured force and the calculated force.
