Power tests and magnetic measurements have been performed on various 1-m-long LHC (Large Hadron Collider) dipole model magnets. Single- and twin-aperture magnets were energized up to peak fields above 9 T. Quench behavior, improvements in the test facility, and losses in the superconductors were examined. The field quality was measured with rotating coils immersed directly in the 1.8 K bath of the vertical cryostat. The design of these coils and the achieved measurement precision are presented. Preliminary measurements of the persistent currents show an unexpected time-dependent decay of the field harmonics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
