If you were to travel parallel to an infinitely long straight wire with current I at the same velocity as the electrons in the wire at a distance a from the wire, the magnitude of the magnetic field (according to your measuring instruments) would be

Two long, parallel wires lie in the x-z plane. One wire passes through the point (−2 m, 0, 0) and the other through the point (+2 m, 0, 0). The wires carry equal currents in the positive z direction. 1. The magnetic field at (−3 m, 0, 0) is in the negative y direction. 2. The magnetic field at (−1 m, 0, 0) is in the positive y direction. 3. The magnetic field at (+1 m, 0, 0) is in the positive y direction. 4. The magnetic field at (+3 m, 0, 0) is in the negative y direction.
