calculator and your notes. Two parallel long straight wires sit beside one another on a wooden table, separated by a distance of 5.0 cm. From your perspective, the one behind carries a 2.6 Amp current North and the one in front carries 1.8 Amp also North. A "top view" of this situation is shown below. North a. What is the magnetic field exactly halfway between the two wires, due to the two wires? include direction (north, south, east, west, up from the table, or down into the table). M6=21167 = 4.167 (2.6+15) 2π(.025) = 2.55.106.(4.4) = 1.12.10-5 1.12.167007 b. Now place a third wire that, for 10 cm, is exactly halfway between the other two, carrying a current of 1.5 Amp due South. What direction is the magnetic force on that wire? c. What direction is the force on the wire you place in the middle due to the Earth's magnetic field?
