The magnetic field \(b^\mu = u_\nu {}^\star\!F^{\mu \nu}\) measured by an observer comoving with the fluid with 4-velocity \(u_\nu\) where \({}^\star\!F^{\mu \nu}\) is the dual of the Faraday tensor. Note that \(b^\mu\) has a time component (that is, \(b^\mu n_\mu \neq 0\), where \(n_\mu\) is the normal to the spacelike hypersurface). More...
