We present results of full-current testing at 4.2 K of a z-axis 0.866-T solenoid and an x-axis 1.225-T dipole coil that comprise a 1.5-T/75-mm room temperature bore magic-anglespinning nuclear magnetic resonance magnet developed at the MIT Francis Bitter Magnet Laboratory. Also included in the paper are results of the magnet performance when the magnet assembly is immersed, to enhance its thermal mass, in solid nitrogen, and operated in the temperature range of 4.2-4.3 K.
