Transport critical current (Ic) was measured for Fe-sheathed MgB2 roundwires. A critical current density of 5.3 x 10^4 A/cm^2 was obtained at 32K.Strong magnetic shielding by the iron sheath was observed, resulting in adecrease in Ic by only 15% in a field of 0.6T at 32K. In addition to shielding,interaction between the iron sheath and the superconductor resulted in aconstant Ic between 0.2 and 0.6T. This was well beyond the maximum field foreffective shielding of 0.2T. This effect can be used to substantially improvethe field performance of MgB2/Fe wires at fields at least 3 times higher thanthe range allowed by mere magnetic shielding by the iron sheath. The dependenceof Ic on the angle between field and current showed that the transport currentdoes not flow straight across the wire, but meanders between the grains
