Abstract
The role of the novel longitudinal vacuum fieldB (3)is discussed in relation to fundamental radiation laws: the Rayleigh-Jeans law, the Planck law, and the Einstein coefficients. The circular index (3) ofB (3)causes electromagnetic energy density to be redistributed from the other indices (1) and (2) of the circular basis, but the presence ofB (3)in the vacuum does not change the value of the Planck constant h. TheB (3)field does not affect, furthermore, the understanding of quantized radiation absorption first proposed by Einstein. Therefore, the experimental observableB (3) does not imply modification of these fundamental, radiation laws, and experimental isolation ofB (3) must take place through its characteristic square root power density dependence when used to magnetize an électron plasma
