This chapter aims to systematically compare and summarize the biological effects induced by static magnetic fields of different directions. We also discuss about the possible mechanisms, which currently is still largely a mystery. We hope researchers in this field can pay attention to the static ...
a已经证明,感应电压使电流的方向与产生电流的磁场力方向相反。 Already proved that, the induced tension causes the electric current the direction with to have the electric current magnetic field strength direction to be opposite.[translate]
This kind of magnetization switching is induced by a microwave field with a duration of 0.5 ns and is clearly dependent on the rotation direction of the microwave field. Magnetization switching of nanomagnets is a core technology in magnetic recording. Conventionally, applying a magnetic field ...
is inducedX on the right hand wing when looking at the diagramThe build-up of charge creates an electric fieldThis creates a force in the opposite direction to the magnetic force(Magnetic) field will be parallel to the wingsSo no force acts (in the direction of the wings) on the (free...
Rule: Stretch the first three fingers of the right hand mutually perpendicular to each other such that the forefinger gives the direction of magnetic field and the thumb points in the direction of the motion of a conductor then, the middle finger will give the direction of t...
The two-dimensional laminar incompressible Navier-Stokes equations and the energy equation with magnetic field force are used to solve the forced convection process of the nanofluid. The displacement currents, the induced magnetic field, the dissipation and the Joule heating in a transient state are ...
The direction of the induced current is determined by the right-hand rule. If the direction of the magnetic field and the direction of the motion of the conductor are perpendicular to each other, the induced current will flow in a direction perpendicular to both the magnetic field and the mot...
It is not convenient, however, for practical use, to compare directly the fluxes X and Y induced by the external magnetic field in the cores I and 2. The method used in the apparatus illustrated by the drawing compares, instead of the fluxes X and Y, the current induced by the additiona...
It is revealed that MNA has a low adhesive gradient along the direction of magnetically induced tilt‐angles. A tilt‐angles of nano/micropillars in the range of 0°–59° is realized by controlling the magnetic field intensity (0–490 mT), so that a droplet (10 μL) can be transported...
