NEAR-FIELDEQUATIONSMODELThe electromagnetic (EM) wave energy is a significant part of the different purposes in the science, technical and engineering sectors. The phase difference between electric and magnetic fields holds important roles to give clear conception of (i) the EM wave energy and (ii...
Electric and magnetic fields are two types of electromagnetic fields that oscillate at different frequencies. When these two fields are out of phase, it means that the peaks and troughs of their oscillations do not line up, resulting in a canceling effect on the overall electromagnetic field. Wh...
Plane Magnetic Field Analysis with the Finite Formulation The paper describes the solution of the static and quasi-static bi-dimensional mag-netic field problems in the framework of the Finite Formulation. The Fin... F Trevisan 被引量: 0发表: 2003年 Flows with cylindrical symmetry A new ...
or some combination of each. When a conductor is placed in aBfield perpendicular to the current, the magnetic force on both types of charge carriers is in the same direction. This force, which can be seen inFigure 5, gives rise to a small potential difference between the sides of the con...
Magnetic fields for the treatment of cancer and to assist in nerve regeneration A device for cancer treatment and nerve regeneration that induces a non-symmetrical electric field. This electric field is thought to cause electro-osmotic activity around p53 proteins within the body, in addition to al...
These quantities are D (the electric displacement vector) and H (the magnetic field intensity). The study of the properties of dielectric and magnetic materials (including subsidiary field quantities and boundary conditions) is not conceptually exciting. This is especially true for ferromagnetic ...
A magnetic field is created. Nothing has changed relative to the amount of matter, its still the exact same amount of atoms, yet through magnetization, a field becomes observable and measureable, its quasi like creating something out of nothing – just like in the beginning of the big-bang,...
Influence of Temperature and/or Field Dependences of the EJ Power Law on Trapped Magnetic Field in Bulk YBaCuO The dynamic response of cylindrical YBaCuO bulk part to magnetic field variations is calculated using the finite difference method. The pulsed field wavefo... K Berger,J Leveque,D Nette...
currents; induced electric fields and currents may also be induced by movement in a static magnetic field, where motion along a field gradient or rotational motion, either in a uniform field or in a field gradient, will result in the change of magnetic flux thereby inducing an electric current...
Roth and Basser analyzed magnetic stimulation of a long, straight axon using a large coil, for which a threshold value of dEx/dx characterized excitation [6]. The same analysis has been applied to microcoils, where the spatial distribution of the electric field varies over short distances compa...
