SUMMARY
The discussion focuses on calculating the electromagnetic momentum of a hollow sphere with a uniform surface charge using Poynting's Theorem and Gauss' Law. The participant correctly identifies the electric field as E = 1/4πε0 Q/a² and proposes the magnetic field as B = 2/3μ0M, where M represents the magnetic dipole moment per unit volume.
