    Well, Laura can't exactly make the magnetic field disappear for the wire outside the 0.025 m section she's considering. The ammeter is also going to be inexact. There might also be some problems with the magnet's field being non-uniform, but unfortunately we don't know what exactly she's trying to measure here.
