THE EARTH`S MAGNETIC FIELD
... • The Earth’s magnetic field can be mapped by means of isomagnetic charts. These are explained on the next page. • Secular variations are slow changes in the Earth’s magnetic field with time. For example magnetic north drifts gradually over the years. • Polarity reversals: There is very strong evide ...

... Each particle experiences the same electric force and the same acceleration. (b) The electric force on the proton is greater in magnitude than the force on the electron but in the opposite direction. (c) The electric force on the proton is equal in magnitude to the force on the electron, but in the ...

To sum up the basic idea of these boundary conditions, the electromagnetic field quantities as well as the moments of the particle distribution function are fixed on constant, timeindependent values in the inner region. Of course, the divergence of the magnetic field vanishes at the grid points insi ...

... the geometric factor BL, we obtain the equation mgu = UI, which virtually relates mechanical and electrical powers and allows m to be determined in terms of electrical quantities and, hence, of the Planck constant. A number of subtleties have been dismissed in the previous analysis. Firstly, the Lor ...

... bound charges. In class we discussed the physical interpretation of bound charges. The displacement of the charges in the material caused by the polarization will only result in a net charge near the surface of the material or near areas where the polarization is not constant, i.e. has a non-zero di ...

... 3.1 MV/m [cf. figure 1(a)], which will be argued to correspond to the anti-crossings at 2.45 and 3.25 MV/m observed in [4], despite of the disagreement in the critical-field values. Let us regard first the dependence of the energy of the ground state on the electric field [figure 1(a)]. This depend ...
