{{ /helmholtz_coil_h1_h2_magnetica.png?900 }} Distribution of [[/magnetic field strength]] //H// along the axis of a [[/Helmholtz coil]], as well as each half of the coil. The values are normalised with respect to the value at the centre of the Helmholtz coil. The distance //x// is zero for the centre of the coil, and the values are also normalised such that the diameter //d// = 1, and radius //r// = 0.5. helmholtz_coil_h1_h2_magnetica.png {{page>insert/file-sz-cc}} {{tag> Magnetic_field_strength_H Helmholtz_coil Helmholtz_coils Current_loop Uniform_magnetic_field Homogeneous_magnetic_field Uniform_flux_density Homogeneous_flux_density Magnetic_field_source Filamentary_coils Thin_coils Files}}
