Direction of electrical current.
... • measure the current in a circuit; • (h) describe Kirchhoff’s first law and appreciate that this is a consequence of conservation of charge; • (b) explain that electric current in a metal is due to the movement of electrons, whereas in an electrolyte the current is due to the • movement of ions; ...

... All Helmholtz coils are oriented such that the separation between the two coils is a (the radius of an individual coil). At this separation, the magnetic field in the midplane between the two coils (i.e., at b = a/2) is very homogeneous. This is shown in the figure below. However, as one moves furth ...
