The light we see from a fluourescent is due to stimulated emmission from the atoms of a phospher coating on the inside of the tube. Photons in the ultra violet are generated by the electrical excitation of mercury vapor inside the tube, these photons strike the phosphers atoms, raising...
Forgive my ignorance .. I'm FAR from being a physicist ..
"that the majority emanate from the poles" .. this would imply the flux density would be greater at the apex then the base ..
if one envisions a parrallel alignment of magnetic domains within the conical shape .. it would seem...
