In free space, unshielded large volume of a low permanent magnetic field (MF) generating system is necessary for use in such areas of magnetic measurements as: calibration of magnetometers, testing of materials, the ecological and medical effects, et

An original operating standard of the unit of magnetic induction gradient, developed at the Mendeleev Institute of Metrology, is described which enables one to calibrate working standards, intended, in turn, for calibrating industrial magnetic gradio

The magnetic field of a single-layer solenoid (length L=1020 mm, average radius R=114.67 mm, pitch p=1.0001 mm and wire diameter d=0.799 mm) with a multi-current method was calculated to improve the uniformity and optimized by using Legendre polynomi

The results of calibration of proton, cesium, potassium and helium–cesium scalar magnetometers in the range 20–100 μT are discussed. The calibration made it possible to estimate errors and to apply corrections to reduce the uncertainty of measur

We report the magnetic-field dependence of the irreversible magnetization of binary superconductor MgB₂. For the temperature region of T < 0.9Tc, the contribution of the bulk pinning to the magnetization overwhelms that of the surface pinning. Th

A working example of a transportable calibration system with reproduction by a highly stable scalar magnetic flux density (MFD) in the range from 20 µT to 100 µT was researched and developed. The random standard deviation was 0.003 nT for a 1 s int

The proton gyromagnetic ratio (/spl gamma/'/sub p/) plays a fundamental role in achieving high accuracy in magnetic measurements. We have improved our magnetic flux density standards using the /spl gamma/'/sub p/-value and related techniques develope

The AC-DC magnetic field standard systems were constructed for the calibration of magnetometers for low magnetic field and the tests for low magnetic field characteristics of sensors and materials. In the range of 1 mT, the expanded uncertainty of dc
