Maxwell, Planck And Particles

From the post "Just Lots of Colors, Retro Disco" Jun2014, where the photon is modeled as a dipole, and the posts "de Broglie Per Unit Volume" and "de Broglie Per Person",

\(h=\cfrac { 1 }{ 8\pi \varepsilon _{ o } } q=2\pi a_{ \psi \,  }mc\)

where \(q\) is the dipole charge.

\(h=\cfrac { 1 }{ 2 \pi\varepsilon _{ o }} \cfrac { q }{ 4\pi a^2_{\psi} }\pi a^2_{\psi}= \oint_{2\pi a_{\psi}}{mc}\,d\,\lambda\)

where the closed looped integral is around \(2\pi a_{\psi}\).

\(h=\cfrac { 1 }{ 2 \pi\varepsilon _{ o }}\oint{ \cfrac { q }{ 4\pi a^2_{\psi} }}\,d\,A_l= \oint_{2\pi a_{\psi}}{mc}\,d\,\lambda\)

where the area integral is over the area, \(A_{a_{\psi}}=\pi a^2_{\psi}\) surrounded by \(2\pi a_{\psi}\).

Differentiating with respect to time,

\(\cfrac{d\,h}{d\,t}=\cfrac { 1 }{ 2 \pi\varepsilon _{ o }}\oint{ \cfrac { 1 }{ 4\pi a^2_{\psi} }}\cfrac{d\,q}{d\,t}\,d\,A_l= \oint_{2\pi a_{\psi}}{\cfrac{d\,mc}{d\,t}}\,d\,\lambda\) --- (*)

Compare this with Ampere's Circuital Law, (The fourth Maxwell's Equation with time varying component set to zero),

\(\mu_o\oint{J}\,d\,A_l=\oint_{2\pi l}{B} \,dl\)

In the first place, the factor of \(\cfrac{1}{2\pi}\) in expression (*) suggests that for a body in circular motion at speed \(c\), its momentum is not,

\(p=mc\)   but   \(p=2\pi mc\)

Consider the centripetal force, \(F\) that accounts for circular motion,

\(p=\int { F } dt=\int { \cfrac { mv^{ 2 } }{ r }  } dt\)

\(\because \cfrac{d\,p}{d\,t}=F\)

Since,

\( \theta =\omega t\)   and \( v=rw\)

\( p=\int { \cfrac { m\left( r\omega  \right) ^{ 2 } }{ r }  } \cfrac { 1 }{ \omega  } d\theta =\int { mr\omega  } d\theta \)

Over one period \(\theta=0\rightarrow\theta=2\pi\),

\( p=2\pi mv\)

And we got it all wrong.  This is important!  We have instead,

\(\cfrac{d\,h}{d\,t}=\cfrac { 1 }{ \varepsilon _{ o }}\oint{ \cfrac { 1 }{ 4\pi a^2_{\psi} }}\cfrac{d\,q}{d\,t}\,d\,A_l= \oint_{2\pi a_{\psi}}{\cfrac{d\,(2 \pi mc)}{d\,t}}\,d\,\lambda\)

Secondly, for a photon \(m=0\), but a change in its \(\psi\) is momentum (from the posts "Bouncy Balls, Sticky Balls, Transfer Of Momentum" and "de Broglie Per Unit Volume"), so

\(\cfrac{d\,(2\pi mc)}{d\,t}=F_\psi\)

is a force that acts on \(\psi\).  Depending on the nature of the photon it may be \(\psi\) along \(t_T\),\(t_g\) or \(t_c\) and one other space dimension, for which the photon is defined.  \(B\) is perpendicular to \(J\) in Maxwell's equation.  The direction of

\(\cfrac{d\,q}{d\,t}\) is also perpendicular to \(F_\psi\)

The nature of \(F_\psi\) depends on the nature of \(q\).  \(q\) is thus qualified as, \(q_{t_T}\), \(q_{tg}\) and \(q_{tc}\) depending on the dimensions between which the photon is oscillating.  In all cases, these include a space dimension, the other being a time dimension, \(t_T\),\(t_g\) or \(t_c\).  So a photon in motion exert a force around it, this force, \(F_\psi\) is a force in space (ie.  \(F=ma\)) and also along one of the time axes \(t_T\),\(t_g\) or \(t_c\).  Previously, in Maxwell's Equation, the effect of the force in the time dimension in which the charge is oscillating has been ignored.  So expression (*) in the case of a photon, ph(\(t_c\),\(t_g\)) is,

 \(\cfrac { 1 }{ 2\varepsilon _{ o }}\oint{ \cfrac { 1 }{ 2\pi a^2_{\psi} }}\cfrac{d\,q_{t_g}}{d\,t}\,d\,A_l= \oint_{2\pi a_{\psi}}{\cfrac{d\,(2 \pi mc)}{d\,t}}\,d\,\lambda= \oint_{2\pi a_{\psi}}{F_\psi}\,d\,\lambda\)

\(F_{\psi}\) then acts on \(t_g\) and a space dimension.

This equation for particles in motion through an area \(A_l\) exert a force field, effecting similar particles, around a loop \(2\pi a_{\psi}\) is just a restatement of Ampere's Law but extended to all particles.  It may be possible that all of Maxwell's equations can be similarly extended.

Let,

\(J_{\psi}=\cfrac { 1 }{ 2\pi a^2_{\psi} }\cfrac{d\,q_{t_T}}{d\,t}\)

 \(\cfrac { 1 }{ 2\varepsilon _{ o }}\oint{ J_{\psi}}\,d\,A_l= \oint_{2\pi a_{\psi}}{F_\psi}\,d\,\lambda\)

This however is using the old definition of \(\mu_o\) and \(\varepsilon_o\).

More importantly, the correct momentum in circular motion,

\(p=2\pi mc=m2\pi c\)

makes \(\mu_o\) and \(\varepsilon_o\) equivalent but orthogonal.

Consider,

\(\varepsilon_{new}=i\mu_{new}\)

\(\sigma ^2=(\cfrac{1}{\sqrt{2}}\varepsilon_{new})^2+(\cfrac{1}{\sqrt{2}}\mu_{new})^2\) --- (**)

\(\sigma ^2=\varepsilon^2_{new}=\varepsilon_{new}\mu_{new}\)

When \(c\) is not in circular motion,

\(c=\cfrac{1}{\sqrt{\mu_{new}\varepsilon_{new}}}=\cfrac{1}{\sigma}\)

as such \(\sigma=\varepsilon_{new}=\cfrac{1}{c}\) is the resistance to \(c\).

When \(c\) is in circular motion, where \(\sigma\) has been resolved into two components as in (**).  Along one of this component,

\(\varepsilon_o=\cfrac{1}{\sqrt{2}}\varepsilon_{new}\)

\(\mu_o\) wrongfully incoperated a factor of \(\cfrac{1}{2\pi}\) when momentum was taken to be \(mv\) and not \(2\pi mv\).  So,

\(2\pi \mu_o=\cfrac{1}{\sqrt{2}}\mu_{new}\)

And so,

\(\mu_o\varepsilon_o=\cfrac{1}{4\pi}\mu_{new}\varepsilon_{new}\)

This means in the expression for \(c\),

\(c=\cfrac{1}{\sqrt{\mu_{new}\varepsilon_{new}}}=\cfrac{1}{\sqrt{4\pi\mu_o\varepsilon_o}}\)

\(\mu_o\varepsilon_o\) has to be adjusted by a factor of \(4\pi\) because the \(2\pi\) factor needed when momentum is circular was not accounted for. (\(2\varepsilon_o\rightarrow\varepsilon_o\) and \(2\pi\mu_o\rightarrow\mu_o\))

\(\mu_o\) is defined as \(4\pi \times10^{-7}\) NA-2.  This is wrong for failing to account for the fact that in circular motion, the momentum is \(2\pi mv\) and not \(mv\).

It is correct and consistent to set

\(\mu_o=\varepsilon_o=\cfrac{1}{c}\)

at the same time, all momentum \(p\) in circular motion is replaced with \(2\pi p\), ie.

\(p_{cir}=2\pi p\)

where \(p_{cir}\) is the momentum in circular motion. Equivalently, all velocity \(v\) in circular motion is replaced with \(2\pi v\).

\(v_{cir}=2\pi v\)

Equivalently,

\(p_{cir}=2\pi p=2\pi mv=m2\pi v=mv_{cir}\)

Correcta, Errata...

Note: This derivation for Ampere's Law applicable to all particles is not rigorous, but indicative none the less.
