The figure below shows two wires carrying currents of I = 5.35 A in opposite directions, separated by a distance d. Assume d = 9.7 cm. Two vertical, parallel wires are separated by a distance d. To the left of the left wire is an arrow labeled I pointing up. To the right of the right wire is an arrow labeled I pointing down. A point P2 is a distance 2d to the left of the left wire, and a point P1 is a distance d to the right of the right wire. (a) Find the magnitude (in µT) and direction of the net magnetic field at a point halfway between the wires. magnitude 44.1 Correct: Your answer is correct. µT direction into the page Correct: Your answer is correct. (b) Find the magnitude (in µT) and direction of the net magnetic field at point P1, 9.7 cm to the right of the wire on the right. magnitude 5.52 Changed: Your submitted answer was incorrect. Your current answer has not been submitted. What is the magnitude of the magnetic field of a long, straight wire? From the right-hand rule, what is direction of the field? Find the vector magnetic field due to each wire at the point of interest, then add the two as vectors to find the net field. µT direction out of the page Correct: Your answer is correct. (c) Find the magnitude (in µT) and direction of the net magnetic field at point P2, 2d = 19.4 cm to the left of the wire on the left. magnitude 11 Incorrect: Your answer is incorrect. What is the magnitude of the magnetic field of a long, straight wire? From the right-hand rule, what is direction of the field? Find the vector magnetic field due to each wire at the point of interest, then add the two as vectors to find the net field. µT direction out of the page Correct: Your answer is correct. (d) What If? Repeat parts (a) through (c) for the case where both wires carry currents in the same direction, upward in the figure. Find the magnitude (in µT) and direction of the net magnetic field at a point halfway between the wires.
