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...
The audio recording was the first type of recording on the magnetic media. The physical principle of the audio recording3 is simple (Fig. 37.1): the amplified ac audio frequency electrical signal is transformed into ac magnetic field signal by the recording head, and this changes the ...

Radial electric currents a actions with the basic magnetic field of a Earth - it turn a kernel. It coincides with laws of electromagnetism. According to a rule of the left hand: if the magnetic field in a kernel is directed to drawing, electric current are directed to an axis of rotation...
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 ...
the proposed cosmological magnetogenesis scenarios using radio and gamma-ray astronomy and ultra-high-energy cosmic rays. We argue that primordial magnetic fields are observationally testable. They lead to magnetic fields in the intergalactic medium with magnetic field strength and correlation length in ...

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...
1 (a). If the magnetic field force is extremely large, the magnetic oscillators will be drawn to each other so that the bilayer membrane will be pulled in the middle. The stacking of magnetic oscillators can adjust the overall vibration characteristics of the membrane structure to control the ...
