22.16Two long parallel wires are separated by a
distance of 2.00 m. The two points P 1 and P 2
divide that distance into three equal parts.
Each wire carries a current in the same
direction. The current I 2 is 3.00 A, as shown in
the illustration, and the current I 1 is "tuned" so
that the strength of the magnetic field at the
point P 1 is zero. (a) What is the strength of the
resulting magnetic field at P 2? (b) Suppose
the current I 1 were re-tuned to produce zero
magnetic field at P 2. What would be the
resulting magnetic field at P 1?
