magnetograph datasolar magnetic fieldpotential fieldsforce free fields/ A9660 Solar physicsSeveral methods currently used to extrapolate the structure of the solar magnetic field from surface measurements are examined and compared. In particular, the differences between the methods of Schmidt for potential...
is absolutely continuous. of course our results only describe the quantum graph model of graphene in a magnetic field, which is both single-electron and high contrast. in particular, we believe that the isolated eigenvalues are unphysical, being an artifact of the graph model which does not all...
the magnetic field vector represented in a global coordinate frame should be stationary when the robot rotates without any translational displacement. Fig. 1 further illustrates this situation. Since this constraint is based
Collapsing magnetic field generates a current. If there is no place for this current to go, the voltage across the inductor will increase instantaneously and then dissipate as the induced current drops off with the drop of the magnetic field. Take a look at the graph shown in Figure 2.43 of...
Direct observation of the Sun's magnetic field became possible around 1950 when the solar magnetograph was constructed. Measurements are done by observing the shift of spectral lines due to the Zeeman effect. At first, the strong magnetic field associated with sunspots (≈ 0.2 T) was detected....
The field lines of a magnetic field run from the north pole to the south pole of the magnet. In the case of a bar-shaped magnet e.g. the poles are mostly at the two ends. That is where the field is strongest. Depending on the shape of the magnet, the field lines run differently...

Some animals can sense the earth's magnetic field (磁场),while humans can't.This magnetic field guides a certain kind of fish when they swim a long way to a place and then back.How can this kind of fish do that?It is still a mystery.Scientists have no good answers ...
