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.

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.

The laboratory electromagnets are mainly used for magnetic hysteresis research, magnetization coefficient measurement, Hall effect research, CI optical experiment, magnetic field annealing, nuclear magnetic resonance, electronic paramagnetic resonance, biological research, magnetic measurement, magnetic material orientation, magnetic product magnetization, etc.

Measurement of various magnetic parameters reflecting the magnetic properties of permanent magnet materials. Also known as hard magnetic material measurement. It is one of the contents of magnetic quantity measurement.

The vibrating sample magnetometer is suitable for the measurement of various magnetic materials (magnetic powders, superconducting materials, magnetic thin films, anisotropic materials, magnetic recording materials, bulk, single crystal and liquid materials)
