Question
The magnitude of the magnetic field produced by a long, straight wire is proportional to the current passing through the wire and
inversely proportional to the distance from the wire.
Consider the five pairs of long, parallel wires shown. The arrows indicate the direction of the current in each wire, with small
arrows representing a current of 4 A and large arrows representing a current of 7 A. For each pair, determine in which one of the
regions the net magnetic field is zero someplace:
• on the left of both wires
• between the two wires
• on the right of both wires
none of the above (i.e., nowhere)
Do not consider distances very far from the wires since in this case the magnetic field always goes to zero.
