Two wires are carrying same size of current and they are oppositve in direction.(One flow into the paper,one flow out of the paper)
Is the magnetic field of the mid point of both wires is stronger,or the regions around both wires is stronger?
Strength of B-field is inversely proportional to distance,but the mid-point seems that is resultant B-field of both wires...quite confused
