A high-performance variable-magnetic-field dipole-ring magnetic circuit is provided. Specifically, provided is a permanent-magnet magnetic field generator comprising inner and outer dipole rings which share a central axis, and a yoke which surrounds the dipole rings, wherein a unidirectional variable ...
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...

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 instrument characteristics and the influence of the spacecraft on the magnetic field measurement will be discussed. The work shows that the applied pre- and inflight calibration techniques are sufficient to suppress spacecraft interferences. The offset in spin axis direction was determined for 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; ...
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 a well ...

The conformal coat is a subtle integration of an open-cavity acoustic absorber made of a dissipative acoustic metasurface (AMS) and a bilayer magnetic cloak. Experimentally, a magnetic cloaking effect with a field disturbance ratio of <0.5% is obtained over a broad-frequency range (10–250 ...
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...
