Principal mechanism. Toroidal magnetic confinement: a magnetic field curves the paths of charged particles; toroidal and poloidal field systems help form a confining helical field in a tokamak. A real plasma also requires a self-consistent equilibrium and transport model, which this exhibit does not compute.
Textbook equations. Ideal toroid: B = μ₀NI/(2πR); single perpendicular proton: r = mₚv/(eB); f = eB/(2πmₚ); magnetic pressure: p = B²/(2μ₀).
Assumptions. Constant field at a chosen ideal radius, μ₀ = 4π×10⁻⁷ H/m, R = 3.4 m illustrative, a representative single proton, and nonrelativistic velocity. Coil counts, currents, and appearance are illustrative—not published reactor ratings.
Scientific vs illustrated. Vacuum chamber, divertor and field coil principles are genuine. Cryogenic routings, supports and dimensions are inspired reconstructions. Glowing flux traces, particle motion, materials, maintenance parts and field uniformity are simplified educational visuals, not validated simulations. The fictional arrangement is speculative.
