Problem

A current, I=1.0 A flows toward west in a straight conductor of length, l=0.25 m.
When a magnetic field, B, perpendicular to the current, is turned on in the region, the conductor feels a downward force of magnitude, |F|=0.50 N.
What are the characteristics of the magnetic field?
Note:
(a) Magnitude, |B|=
