WebBy placing these rings a specified distance apart from each other, a uniform magnetic field is eventually developed. Once the best distance is obtained, the two coils become known as Helmholtz coils. The intensity of a magnetic field gets measured from three separate coil spacings, where each distance creates its own magnetic field.
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. in another dayWebTasks. The magnetic flux of a pair of Helmholtz coils is to be determined and plotted graphically as a function of the coil current.
