The Abraham-Minkowski controversy is a Physics debate concerning Electromagnetic Momentum within Dielectric media. The preponderance of evidence in the debate suggests that the Abraham equation {Link without Title} is correct, but some investigators disagree. Two equations exist describing momentum transfer between Matter and Electromagnetic Field s - both seem to be supported by contradicting experimental data. The two existing equations were first suggested by Max Abraham and Hermann Minkowski - from which the controversy name derives. Both define the momentum of an electromagnetic field permeating matter. Abraham's equation suggests that in materials through which light travels more slowly, electromagnetic fields should have lower Momentum - Minkowski suggests it should have a greater momentum. It has been discovered that while Abraham only accounts for the momentum of the electromagnetic fields, Minkowski takes into account the momentum of the material also. Some suggest that Vacuum fluctuations contribute to the motion of dielectric liquids in crossed electric and magnetic fields. If correct, this phenomena could be used to investigate Zero-point Energy . EXTERNAL LINKS REFERENCES {Link without Title} Quantum vacuum contribution to the momentum of dielectric media, A.
