I Wire A B Wire B 21 B One wire A, is the magnetic field stronger at points closer to the wire (inner circle) or farther from the wire (outer circle)? One wire B, is the magnetic field stronger at points closer to the wire (inner circle) or farther from the wire (outer circle)? Compare the magnetic field vectors for the same distance (ie, same circle) for wires A and B. Which wire produces a greater magnetic field? What is different about wires A and B that might cause a difference in the magnetic field?
