Helmholtz coil introduction
The Hermann von Helmholtz coil is composed of a pair of identical circular conductor coils. The central axis of these two circular coils with a radius of R is coaxial with the Z-axis. The spacing between two circular coils is h=R. The turns of two circular coils.The number is the same, and each conductor coil carries the same directional current I, with a good linear relationship between the current value and the magnetic field value.

The solenoid testing method for austenitic materials
Austenitic stainless steel has excellent corrosion resistance and is widely used in industries such as petroleum, chemical, power, and atomic energy. In the process of processing, cold rolling, cold drawing, cold bending, leveling and correction and other cold working processes will lead to deformation, which will change part of the austenite phase to martensite phase, that is, deformation induced martensite transformation.
