FIG 3.0 - PERFECT DIAMAGNETISM & STATIC FLUX EXPULSION

Superconductive Physics

The "Faraday Cage for Gravity"

A 54.4 Giga-Watt electrical pulse discharge inside the FSS-02 Stator generates a transient magnetic field ($B$) so violently intense that it would instantly ionize human blood. Traditional lead or copper shielding is useless against this Giga-Tesla scale pulse.

The Critical Field ($H_{c2}$) Limit & Perfect Diamagnetism

The goal is to orchestrate Perfect Flux Expulsion ($\chi = -1$) during the 1ms Snap. This ensures the magnetic field lines from the GATE-01 induction ring are violently forced to flow around the titanium hull rather than through it.

Meissner Expulsion Condition:

$$ B = \mu_0 (H + M) = 0 \quad \text{for} \quad T < T_c \text{ and } H < H_{c2} $$

REBCO Physics: Standard Type-I superconductors quench (fail) if the magnetic field is too strong. The STR-01 utilizes Silver-sheathed REBCO (Rare-Earth Barium Copper Oxide) 2G High-Temp ribbons because its upper critical field limit ($H_{c2}$) exceeds an astonishing 100 Tesla when flash-frozen to 4 K.
The Expulsion Engine: As the 54.4 GW pulse hits, the FSS-02-C Shielding Cage generates millions of amperes of surface currents ($J_s$) that instantly create an equal and exactly opposite magnetic field.
The Result: The interior of the ship (the crew cabin) remains at < 0.5 mG (milliGauss), while the exterior hull skin routinely survives handling a massive 4.2 T magnetic flux wake.

Eddy Current Suppression: The STR-07-A SF6 Arc Buffer

Because the Snap occurs in only 1 millisecond ($1\text{ms}$), the rapidly changing magnetic field ($\frac{dB}{dt}$) induces colossal Faraday currents. Any generic, non-superconducting metal inside the hull framing (like the Titanium support lattice) would instantly experience massive induced Eddy Currents, resistively heating the ship until it melts into slag.

Engineering Solution: We saturate the structural gaps between the Titanium members with Sulfur Hexafluoride ($\text{SF}_6$) gas. This provides an absolute dielectric lockout (3x the breakdown voltage of air), safely smothering arc-flashes and preventing the 54.4 GW pulse from randomly jumping or arcing across hull segments.
