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




• 100 kA at 1 mm radius is 20 T
• 10 MA at 4 mm radius is 500 T
• 100 kA at 1 um radius is 20 kT

# magnetic pressure




• 100 kA at 1 mm radius is 1.6 kBar
• 10 MA at 4 mm radius is 1 MBar
• 100 kA at 1 um radius is 1.6 GBar

# Bennett condition

• magnetic pressure = plasmakinetic pressure
• 100 kA at 1 um radius is about 1.6 GBar of plasma pressure (wau!! really??!!)
