MAGNETIC fields are used extensively in practice to help control the position or motion of an electric arc. Properly applied, they can be used as an aid to either the stabilization or extinction of an arc. Improperly controlled, they may introduce unwanted instability to an arc.Winsor, L. P...
To be used as a magnetic field sensor in different applications, the possibility of tuning the performance of the MTJ is important. Different means of tuning, such as voltage and magnetic field biasing, can be used. In this work, an external magnetic field from a permanent magnet was used ...
By means of the density matrix renormalization group (DMRG) method, the magnetic properties of the J–J–J ' quantum Heisenberg chains with spin S = 1/2, 1, 3/2 and 2 in the ground states are investigated in the presence of a magnetic field. Two different cases are considered. (a)...
Over a wavelength range (888–2500 nm), the enhancement of the infrared absorption of CNMF_6h is up to 1.85 times compared with the T_FW. Furthermore, infrared excitation induces a photothermal effect that results in variation in the magnetic properties of the carbon-matrix Ni wing. The ...
The properties of an exciton at the surface of a polar cryrstal in a weak magnetic field B, which is perpendicular to the surface and is constant, are discussed by a perturbational method with which Shi-wei Gu studied the problems of excitons. Taking account of the effects from the surface...
The properties of water and their changes under the action of a magnetic field were gathered by the spectrum techniques of infrared, Raman, visible, ultraviolet and X-ray lights, which may give an insight into molecular and atomic structures of water. It was found that some properties of water...
Magnets make invisible areas around them called magnetic fields. The magnetic flux is the space around a magnet where you can feel its force. To see the magnetic flux, we draw magnetic field lines. More lines mean a stronger magnetic field. The lines come out of the magnet's north pole ...
Magnetorheological(MR) fluids are a class of new intelligent material whose rheological characteristics change rapidly in the presence of an applied magnetic field. The main characteristics and the operation modes of MR fluids have been analysed, the applications of MR fluids devices in engineering fiel...
