• high energy density plasma pressure

[math]1 MBar = 1 \times 10^6 \times 10^5 Pa = 10^{11} Pa = 10^{11} (N m)/(m^2) = 10^{11} J/m = 10^{11} (10^7 erg)/(10^6 cm^3) = 10^{12} erg/cm^3[/math]

• magnetic field produced by single wire (Ampere law / Biot-Savart Law)

[math]B[G] = \frac{I[A]}{5r[cm]}[/math]

100 kA at 1 um radius is 200 MG

• magnetic pressure

[math] P_{magnetic}[bar] = (2 \times B[T])^2 \sim I^2 \times R^{-2} [/math]

[math] 5 \times 10^6 G \Rightarrow 1 MBar [/math]

[math] 200 \times 10^6 G \Rightarrow 1600 MBar [/math] wau!!!
