(3) Two long straight wires carry currents L}, as shown, one into the page, the other out of the page. Let 5 boxes on the graph be considered a distance D. (a) Sketch the magnetic field lines due to each wire as they pass through point P. Sketch the net field vector. Write a vector expression for the magnetic field at point P. = out of the page = into the page (b) You want to place a third wire somewhere parallel to the other two, also carrying current {0, such that the magnetic field at pointP becomes zero. Find the location of the third wire (mark it on the graph) and the direction of the current (into or out of the page). Hint: there are two locations possible. II _ - . , C9 = out of the page = into the page
