We examine metal lamina in which under the action of electric field E_i there is
current i_- from electrons with mean velocity 1- = const. We have constant
magnetic field with induction B = const, whose lines are perpendicular to the
metal lamina. The vector of velocity v_- is collinear with the vector of the electron
current i_- . The vectors i_- and B define electrodynamic field E_md by:

—7                       —7

(92)               Emd = ^v × B

The electromagnetic force F_M , which acts upon N moving electrons, is:

(93)              F_m = eNv_- × B

The electromagnetic force F_M has the opposite direction of E_md , thus the side M
is polarized negatively, while M’ is polarized positively. Between M’ and M there
is excited potential electric field with intensity E_H . The vector E_H has the
opposite direction of E_md . The respective force F_H is defined as:

7                     7

(94)              FH= eNEH

is the opposite of F_M . The polarization between M’ and M is over when the two
forces F_M and F_H get equal. The current is still flowing but the vector J_- and the
resultant field E are no more collinear, instead they form the Hall angle θ_H . Then
the Ohm’s law J_- = γE is not valid (γ is the specific conductivity of the metal).

The calculation of θ_H is simpler when we have monotype current carriers (in our
case electrons). If we have equilibrium
