THE use of two equal and co-axial circular coils of wire, separated by a distance equal to their common radius and traversed by the same electric current in the same sense, has long been the standard practice for producing a nearly uniform magnetic field throughout an appreciable volume. The...
The meaning of HELMHOLTZ COIL is one of two equal parallel coaxial circular coils in series that are separated from each other by a distance equal to the radius of one coil for producing an approximately uniform magnetic field in the space between the co
The TM2300 / TM2330 is a series of Helmholtz coils. The generated magnetic field has good linearity with the current, and the standard DC magnetic field can be generated with the precise excitation current source. 2. Applications Calibration of magnetic sensors Calibration of magnetometers Electroma...
Helmholtz CoilsHelmholtz-Coils are especially designed to generate precisely defined magnetic fields from DC to the upper end of the audio frequency range and beyond. The generated fields are in a strongly linear relation to the coil current. The field- strength can be calculated exactly by ...
Use two coils with exactly the same radius and number of turns and arrange them coaxially and make the distance equal to the radius. This combination of coils is called a Helmholtz coil. It can generate a very weak magnetic field up to hundreds of Gs; the coil has a large uniform area,...
Helmholtz-Coils are therefore ideally suited for the calibration of magnetic field probes or sensors, where the coil current is proportional to the magnetic field strength when the coil generates a magnetic field. Selection: The following table shows a collection of Helmholtz-Coils models manufactured...
A Helmholtz coil is a pair of co-axial circular coils of current arranged to produce a fairly uniform magnetic field between the coils by setting the distance between the coils equal to the coil radius.Fig. 55 Figure: SIMION simulation (Biot-Savart) of two wire coils, showing magnetic field...
