Electromagnetic mass ( longitudinal mass) by Lorentz
Due to the self-induction effect, electrostatic energy behaves as having some sort of momentum and “apparent” electromagnetic mass, which can increase the ordinary mechanical mass of the bodies. Electromagnetic radiation energy has momentum and mass.
The electromagnetic mass depends on the direction of the moving bodies with respect to the aether. The longitudinal electromagnetic mass is related to the mass of an electron at rest and the speed of light.
|mL||The longitudinal electromagnetic mass (in the longitudinal direction) (kg)|
|v||The speed of radiation (m/s)|
|c||Speed of light|
