Can I alter the quanta of magnetic flux using length contraction of the source creating the B field. Like for example could I get half of the flux by moving relative to the B field. Or some other fraction of it. The unit of flux is like $\frac{h}{2e}$

The magnetic flux is actually a scalar quantity which doesn't change from Lorentz boosts. This is because while the magnetic field changes, the area also changes in exactly compensating ways.

ok interesting, what about the Planck length

What about it? It's just a unit of measurement, like the meter. It doesn't really mean anything special except we expect that at those lengths (i.e. order of magnitude near the Planck length), space-time might look different.

If there is a minimum length, then i could just move by it a speed and length contract it.
Or maybe this doesn't matter.
