However, these fields can The subindex or super index in some four-vectors be represented in terms of potentials, which need are only a matter of notation, in order to distinguish only four parameters: Therefore, from other variables.

Besides, in our previous expression 9 there appears The four-vector product is computed with the for- a scalar term first term of the four-vector , which mula: Each position in the spatial part of this four- vector is a single complex variable, constituted of the corresponding electric and magnetic field in the In order to derive the formulas for electromag- respective coordinate direction.

Its form is identical to the Lorenz gauge. However, if such were the case, as shown below.

Expanding this expression with the use of the formula for the product 4: The current density four-vector is the classical one [9, Eq. However, there is no evidence of such force in And the fields already include the the corresponding classical equation of forces.

This equation is electrodynamics handles the electromagnetic fields essentially the one appearing as equations However, notice that, as shown in our and magnetic fields.

The result is identical charge, q1 , is found on the x-axis, with that this field is not affected by the transformations, its velocity, v1 , pointing along the x-axis, as in the which looks suspicious. On the other hand, in our theory let us apply v1 q1 q2 equation 23; let us assume that the field is at the origin and the scalar field s is equal to Ex , which The relativistic electric field of particle 1 at the makes the field invariant equal to zero, and that the position of particle 2 is given by Jackson [9, Section observer is moving away from this field towards the 11], [Eq.

The result is a redshift of the form zero] and used also by Jefimenko [22], Caprez [23] s and others: In order to obtain this last result, the signs of the terms containing s should be interchanged in The trouble with this equation is that the electric equations 22 and 23 these equations are obtained and magnetic fields should not change when they with application of the alternative product, instead are perceived by an observer in the direction of mo- of 4.

Let us assume that the electric field of the charge q1 , To counterbalance this discrepancy, the classical considered at rest in its proper frame of reference, is authors obtain essentially the difference between E12 , at the distance where charge q2 is located. Therefore, the appears incorrect. But, for The apparently innocent addition of a new scalar the case of the charge q1 , which is identical to field, in order to complete the electromagnetic four- q2 , the classical equations for transformation of vector, proves to transform electromagnetic theory electromagnetic fields do not produce any effect radically.

In summary, all the supervening changes in the direction of motion. Therefore, the only appear to correct standing problems, such as in the known field for that charge, which is E12 , should Lorentz forces equation, in the transformations for preserve the invariant.

The electrical and electronic practitioners, such Therefore, it seems that classical electrodynam- as the ones from the Institute of Electric and ics handles incorrectly the electromagnetic fields.
