[Python] How to calculate and plot field map from a current carrying wire using Magpylab?

I am using Magpylib package to plot 3D or 2D map of field from a current carrying wire. There is a code for older version of Magpylib (below).

s4 = magpy.source.current.Line(curr=10, vertices=[(0,-5,0),(0,5,0)])

This is what I expect :

I have changed the code as below to get the expected plots. But the B values are way low and the streamplot does not seem to work.

This is what I get

current = 10 length = 10e-6 # 10 µm

Create a short straight wire along x-axis wire = magpy.current.Line( current=current, vertices=[[-length/2, 0, 0], [length/2, 0, 0]] )
