Helmholtz coil

A Helmholtz coil consists of two identical circular wire coils positioned parallel to each other, separated by a specific distance equal to their radius. When an electric current flows through the coils, they produce a uniform magnetic field between them. This setup is used in experiments and applications requiring a stable, predictable magnetic environment, such as calibrating instruments or studying magnetic properties. The design minimizes variations in magnetic field strength within the central region, making it ideal for precise scientific work.
