Two long parallel conductors carry currentsandin the same direction. The magnetic induction at a point exactly midway between them is. If the current in the first conductor is reversed in direction, the magnetic induction at the same point will be
Options:
Answer:
C
Solution:
In the first case, the two fields are in opposite directions and as a result, the resultant field is the difference of the individual fields whereas, in the next case, the two fields are in the same direction and add up to give the resultant.
