Problem

Two long parallel straight conductors are

6.0\,\text{cm}

apart in air. They carry currents of

20\,\text{A}

and

30\,\text{A}

in opposite directions. Find the point(s) along the line joining the wires where the resultant magnetic field is zero. Measure the distance from the

20\,\text{A}

wire.
