A long, straight wire carrying a current of 317 A is placed in a uniform magnetic field that has a magnitude of 7.69 × 10-3 T. The wire is perpendicular to the field. Find a point in space where the net magnetic field is zero. Locate this point by specifying its perpendicular distance from the wire.

  1. I=317 A
    B=7.69•10⁻³ T

    B(wire)=B
    B(wire)=μ₀I/2πa =B
    a= μ₀I/2πB=
    =4π•10⁻⁷•317/2π•7.69•10⁻³=8.24•10⁻³ m
