Most variables have units which are obvious, but E (electric field) and B (magnetic field) should be stated in terms of the Gaussian units used for derivations. +--+ Limit CHECKS Dimensional consistency : From file "Howell - Variables, notations, styles for Bill Lucas, Universal Force.odt" sub-sub-section "Dimensional analysis (Gaussian units)" : As a convention here take [unit vectors, c] as dimensionless . OK, as all terms reduce to the same unit dimensions. All derivations below ignore permittivity & permeability for Gaussian coordinates, except that of F, which requires these factors to balance units? Example : From "Howell - Key math info & derivations for Lucas Universal Force.odt" sub-sub-section "E0pdv(POIo,t) = E0odv(POIo,t)" Units of measure Gauss's Law for a single point charge, in the particle reference frame (FRp) : 1) E0pdv(POIo,t) = E0odv(POIo,t) = Q(particle)/Rpcs(POIo,t)^2*Rpch(POIo,t) E units = (charge/length^2) (ignoring permittivity & permeability for Gaussian coordinates) dp[dt : E] units = (charge/length^2/time) B units Example : From "Howell - Key math info & derivations for Lucas Universal Force.odt" (ignoring permittivity & permeability for Gaussian units) sub-sub-section "BTodv(POIp,t) = BTpdv(POIp,t) " Generalized Ampere's Law : BIpdv(POIp,t) = Vpnv(POIp)/c X E0pdv(Rpcv(POIp)) units = (length/time)*(charge/length^2) = (charge/length/time) dp[dt : B] units = charge/length/time^2 F (force) ignoring permittivity & permeability for Gaussian coordinates from my correction to (4-06) and taking "c" as dimensionless F(r,v,t) = F(r,v,t) = q*[ E(r,v,t) + v/cB(r,v,t) ] units = charge*[ (charge/length^2) + (length/time)*(charge/length/time) ] = charge^2/length^2 + charge^2/time^2 OOPS!! This doesn't work at all!!! If I insert permittivity (ε) and permeability (μ) : from : https://simple.wikipedia.org/wiki/Maxwell's_equations#The_structure_of_the_magnetic_field ε = permittivity = F/m (F = Farads) μ = permeability = W/(A*m) = Power /charge/length = mass*length/time^3/ charge/length E -= electric field = V/m B = magnetic field = H (H = Henrys)
