WebIn the case of the Helmholtz coils, the field points of interest are located in the mid-plane between the two coils. As shown in the equation above, the strength of the magnetic field is dependent upon three quantities: the current I, the number of turns N in each coil, and the radius a of the coil. The total current in each coil is NI. WebHelmholtz coils are formed by a pair of identical coils with separation equal to their radius, Figure 2. Figure 2 Helmholtz recognized that coils of this nature carrying a current I circulating in the same sense produced a magnetic field midway between the coils that is especially uniform. The field along the axis midway between the center of both
