In Oersted's experiment, suppose that the compass was 0.15 m from the current-carrying wire. If a magnetic field of one third the Earth's magnetic field of 5.0×10−5T was required to give a noticeable deflection of the compass needle, what current must the wire have carried? Express your answer using two significant figures.
