Measurements of the polarization of the far-infrared thermal emission from six points in the dust ring at Sgr A are presented. The position angles are approximately perpendicular to the long axis of the ring as projected on the sky. The inferred magnetic field is therefore approximately in the ...

The system is based on a nulling field coil fed by a current on the basis of the residual field, sensed by a magnetic sensor (Hall or magnetoresistive) placed in the coil center. In this way, the coil current proportionally represents the external field component along the coil axis, and...
PURPOSE:To reduce the number of magnets and to set the intensity of magnetic field easily and simply by using permanent magnets and a superconductor at the bearing portion and the shaft portion of a magnetic bearing which supports the load in the axial direction. CONSTITUTION:The load in the ...
The magnetic field of the Earth has global meaning for a life on the Earth. The world geophysical science explains: - occurrence of a magnetic field of the Earth it is transformation of kinetic energy of movements of the fused iron in the liquid core of Earth - into the magnetic energy; ...
At 10T, the change in the soft-mode frequency is ∼-0.2%. Converted to shifts in the Curie temperature with magnetic field, the data indicate that T0(H)-T0(0) ∼ 5 × 10-4 H2 + 7.5 × 10-6 H4 (H in Tesla). These data are consistent with recent neutron measurements on ...
PURPOSE:To enable the measurement of a magnetic field in a wide range at a high accuracy, by arranging an axis of easy magnetization of a magnetooptic element vertical to the direction of the magnetic field to be measured. CONSTITUTION:A light source 11, a polarizer 212, a thin filmlike ...
These bumps become less pronounced with increasing Bext, as the cone phase approaches a field-polarized state. e Dependence of twist angle on distance to the lower surface for the five skyrmions that wind around a central sixth skyrmion. The angles φi(z) are measured from the x axis, as...
Uniform magnetic field exists only in a cylindrical space with radius R=4, and it changes as dB/dt = 3. How much is the induced electric field at point P with distance r=10 from the central axis of cylinder? (SI units) E = ___. 暂无答案...
The magnetic field is one of the main causes of zero drift in a Ring Laser Gyroscope (RLG), which should be avoided by adopting a magnetic shielding system. The Gauss Meter is usually used to measure the magnetic shielding effectiveness. Generally, the traditional Gauss Meter has advantages of...
