Here I investigate the relation between ×lt;igt;lt;bgt;Blt;/bgt;lt;/igt; and lt;igt;lt;bgt;Jlt;/bgt;lt;/igt; in the same terms and by the same method as previously applied to the MHD relation between the electric field and the plasma bulk flow vmv2001: assume that one but not...
With our current incorrect understanding of energy being limited, we conclude that the permanent magnet doesn’t spin, doesn’t oscillate, yet on atomic scale, the permanent magnetic field created by the permanent moving charge of the permanent electron oscillates and spins. They are the same, ye...
The detection of faint magnetic fields from single-electron and nuclear spins at the atomic scale is a long-standing challenge in physics. While current mobile quantum sensors achieve single-electron spin sensitivity, atomic spatial resolution remains el
The magnetic field of the resultant current density is calculated in terms of the electrostatic field of the charge distribution. The relation is of greatest utility in the calculation of the magnetic field of a rotating spherically symmetric charge distribution in terms of its electrostatic potential...
We derive exact expressions for remote electric and magnetic fields as a function of the time- and height-varying charge density on the lightning channel for both leader and return-stroke processes. Further, we determine the charge density distributions for six return-stroke models. The charge dens...
77 Modification of Electric and Magnetic Fields by Materials In the absence of an applied electric field, the molecules of a dielectric are randomly oriented (Fig. 5.1b). This results from the disordering effects of thermal molecular motion and collisions. Molecular ordering cannot occur ...

[Uman and McLain, 1969] of the return stroke provides a fairly good representation of the relation between the waveforms and peak values of the measured current derivative and the measured electric and magnetic field derivatives at 15 m for assumed return stroke speeds between 2 and 3 × 108 ...
Transverse magnetic field. The spin orientation does not change in relation to the direction of propagation. Longitudinal electric field. Though the beam is accelerated (or retarded) the spin orientation remains constant in space. Longitudinal magnetic field. The spin orientation rotates about the ...
We take out "formulas" for electric potential from the relation $$V=\int E.dx$$ Some general formulas are : For a hollow sphere : ##\frac{Q} {4π\epsilon_0 x}## when x>R, x =distance of that point from the center And the problem is we just input the distance in sums to ...
