• 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]P_{magnetic} = \frac{I(A)}{5r(cm)}[/math]

• • 100 kA at 1 um radius is 200 MG

• plasma magnetic pressure (Bennett equation)

[math] B^2 \simeq I^2 \times R^{-2} [/math]

• • [math] 5x10^6 G = 1 MBar [/math]
  • [math] 200x10^6 G = 80 MBar [/math]
