Megaamps, Megagauss, and Megabars: Using the Sandia Z Machine to perform extreme material dynamics experimentsMarcus KnudsonAmerican Physical Society
Voltmeters are fairly inexpensive and easy to find, but where do you purchase a Gaussmeter (also known as a magnetometer). I built a hand-held Gaussmeter for measuring the polarity and strength of a magnetic field. It uses a linear Hall effect device and some op-amps and resistors and ...

An alternate option is to remove the capacitors and directly power the coil from high-current batteries. This solves the long recharge time problem, but introduces another problem: even the best portable batteries can only supply a few hundred amps, so the battery-powered coil is very weak and...

Short test samples of 75% Nb--25% Zr base alloy wire were found to carry between 20 and 40 amps at 20 kgauss and 4.2-K. With the maximum permissible current in each section, a magnetic field slightiy over-43000 gauss was generated in the center of the solenoid at 4.2 f K. The ...
The final persistent current is 175 amps. The maximum field reached 25,000 oersteds corresponding to somewhat less than 18 amps per wire, the critical current carrying capacity. The pumping speed for the coil was approximates 20 gauss per revolution of the rotor, nearly linear over the whole ...
Electric contact, eps. for circuit brakers rated at 40-4000 amps. at a magnetic blowout field strength of 50-500 gauss, consists, at least in the contact layer, of a composite of Ag and fibrous embedded SnO2, the SnO2 fibres being aligned parallel and perpendicular to the switching plane....
