A Helmholtz coil Helmholtz coil schematic drawing. A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz. It consists of two electromagnets on the same axis, carrying an equal electric current in the same direction. Besides creating magnetic fields, Helmholtz ...
Helmholtz's polyphonic siren, Hunterian Museum, Glasgow. Hermann Ludwig Ferdinand von Helmholtz (/ ˈ h ɛ l m h oʊ l t s /; German: [ˈhɛʁ.man vɔn ˈhɛlmˌhɔlts]; 31 August 1821 – 8 September 1894; "von" since 1883) was a German physicist and physician who made significant contributions in several scientific fields, particularly hydrodynamic stability.

Two coils in an anti-Helmholtz configuration are used to generate a weak quadrupolar magnetic field; by convention, the coils are separated along the -axis.In the proximity of the field zero, located halfway between the two coils along the -direction, the field gradient is uniform and the field itself varies linearly with displacement from the field zero.
Teltron electron beam tube Teltron deflection tube with Helmholtz coils and stand. A teltron tube (named for Teltron Inc., which is now owned by 3B Scientific Ltd.) is a type of cathode-ray tube used to demonstrate the properties of electrons.
Maxwell's geometry of the coils. A constant-field Maxwell coil set consists of three coils oriented on the surface of a virtual sphere. [1] According to Maxwell's original 1873 design: [2] each of the outer coils should be of radius , and distance from the plane of the central coil of radius .

The Helmholtz equation has a variety of applications in physics and other sciences, including the wave equation, the diffusion equation, and the Schrödinger equation for a free particle. In optics, the Helmholtz equation is the wave equation for the electric field. [1] The equation is named after Hermann von Helmholtz, who studied it in 1860. [2]
English: Cross section of B (magnetic field strength) magnitude in a Helmholtz coil (actually consisting of two coils: one at the top, one at the bottom in the plot). The eight contours are for field magnitudes of 0.5 {\displaystyle B_0}, 0.8 {\displaystyle B_0}, 0.9 {\displaystyle B_0}, 0.95 {\displaystyle B_0}, 0.99 {\displaystyle B_0}, 1.01 {\displaystyle B_0}, 1.05 {\displaystyle B_0}, and ...
