Profiles of noninductive current driven by neutral beam injection into a tokamak have been measured and compared with theory. The driven current can be less than the theoretical prediction (by up to 80{percent}) in the presence of islands driven by tearing modes. {copyright} {ital 1997} {ital The American Physical Society}
