1. A wire runs from north to south        a. A compass needle placed above the wire points with its north pole        toward the east. In what direction is the current flowing?         b. If a compass is placed underneath the wire, in which direction will its needle point?   2. What will be the direction of the magnetic field if the current is due upward?   3. How does the magnitude of the current passing through the conductor affect the magnetic field?
