# magnetic field produced by single wire (Biot-Savart Law)




• 10 MA at 4 mm radius is 500 T
• 100 kA at 40 um radius is 500 T
• 160 kA at 5 um radius is 6,400 T

# magnetic pressure




• 10 MA at 4 mm radius is 1 MBar
• 100 kA at 40 um radius is 1 MBar
• 160 kA at 5 um radius is 164 MBar

# Bennett condition

• magnetic pressure = plasmakinetic pressure
• 100 kA at 40 um radius is 1 MBar of plasma pressure
• 100 kA at 1 um radius is 1.6 GBar of plasma pressure
