9. Equation (2) indicates that the magnetic field vector can be written as a gradient of a scalar magnetic potential function $$\begin{aligned} \varvec{B}= -\nabla \Phi _M(\varvec{r}). \end{aligned}$$ (3) Substituting (3) into Eq. (1) tells us that the magnetic scalar ...
The mean magnetic field equation describes the process of generating a magnetic field on a large scale as a result the EMF arising on a small scale. We consider the case where the large-scale magnetic field is also random and determine the density function of magnetic helicity. This function ...
Magnetic field and magnetism are the aspects of the electromagnetic force, which is one of the fundamental forces of nature [1–3] and remains an important subject of research in physics, chemistry, and materials science. The magnetic field has a strong influence on many natural and artificial ...

Only when the charge is in motion will a magnetic field exert a force on it. This magnetic force increases whenever we increase the magnetic field strength, or the charge on the particle, or the speed with which the particle moves. The equation that describes these features of the magnetic ...
It is generally assumed that Fe-decorated magnetic tips have large magnetic anisotropies and that a change of the external magnetic field direction may cause the tip field to flip by 180° along an easy axis38. According to equation (1), in the absence of electric and magnetic dipole moments...
