    "abstract": "Magneto-optic and magnetostatic trapping is realized near a surface using\ncurrent carrying coils wrapped around magnetizable cores. A cloud of 10^7\nCesium atoms is created with currents less than 50 mA. Ramping up the current\nwhile maintaining optical dissipation leads to tightly confined atom clouds\nwith an aspect ratio of 1:1000. We study the 3D character of the magnetic\npotential and characterize atom number and density as a function of the applied\ncurrent. The field gradient in the transverse dimension has been varied from \u003c\n10 G/cm to \u003e 1 kG/cm. By loading and cooling atoms in-situ, we have eliminated\nthe problem of coupling from a MOT into a smaller phase space.",
