I need help correcting this

\fFigure (a) shows an element of length ds = 1.07 um in a very long straight wire carrying current. The current in that element sets up a differential magnetic field d B at points in the surrounding space. Figure (b) gives the magnitude dB of the field for points 5.1 cm from the element, as a function of angle 0 between the wire and a straight line to the point. The vertical scale is set by dB, = 62.4 pT. What is the magnitude of the magnetic field set up by the entire wire at perpendicular distance 5.1 cm from the wire? ds- Wire (a) dB, dB (pT) 0 1/2 0 (rad) (b) Number 5.65E-4 Units Tom V
