Again somewhat technical, so I apologize.
If we look at Maxwell's Equations and restate them in a more complicated form...
To break it down in a handwaving sense, the φ is essentially the voltage (in technical terms we call it the scalar potential of the electric field). The equivalent for magnetism is the "A", which is a vector and electrodynamics boffins have varying interpretations of what it actually means. For the purposes of my discussion it turns out that if you look carefully, "A" actually represents a kind of electromagnetic momentum, that is, the movement of charged particles.
This should make sense since magnetic fields normally get generated by charges in motion, so you can think of voltage (φ) as the generator of the electric field, just as charge-momentum (A) is the generator of the magnetic field.
Now, recalling that in Revolution-world, one hypothesis which I elaborated on previously is that the magnetic field is decoupled from the electric field.
If that's so, then in effect the electromagnetic momentum can no longer generate magnetic fields, so we set A to zero.
Result? Selectively looking at the equations with the easiest physical meaning (orange boxes),
No magnetic fields (B = curl 0 = 0)
No electric fields from magnetism; only from setting up a voltage (E = spatial distance of voltage - 0)
No electric currents (space-time motion of zero = zero electric current)
The other more complicated equations will ultimately boil down to the same physical meaning (no technology possible that depends on electricity).
And now for spoilers!
