We consider a staged Z pinch in which an annular plasma implodes onto a coaxial wire. The physical model involves conservation of magnetic flux created by the current initially trapped in the wire plasma and adiabatic heating. It leads to magnetic-field and current amplification with a current rise time of 4 × 1015 A/sec. At peak current levels approaching 5 MA the wire plasma attains a density n=1024 cm-3, a temperature T=10 keV, and nτ>1015 cm-3 sec.
