    "abstract": "We present a quantitative study of roughness in the magnitude of the magnetic\nfieldproduced by a current carrying microwire, i.e. in the trapping potential\nfor paramagnetic atoms.We show that this potential roughness arises from\ndeviations in the wire current flow due to geometric fluctuations of the edges\nof the wire : a measurement of the potentialusing cold trapped atoms agrees\nwith the potential computed from the measurement of the wire edge roughness by\na scanning electronmicroscope.",
