Magnetic Induction
Two long parallel straight conductors carrying currents and in same direction and are separated by a distance of . Calculate the distance of the point where resultant magnetic induction due to the currents is zero.
Details & Assumptions
- The distance is measured from the wire carrying the current of .
The answer is 0.075.

Use the formula for field due to straight wire and see that I/R is the proportionality. Further since the field due to both is cancelling so equate them. Take the distance from the first one to be X and other yo be 0.3- X. So the answer will come out to be 0.075
