Question

The figure below shows two wires carrying currents of I = 4.75 A in opposite directions, separated by a distance d. Assume d = 11.0 cm. P2 2d (a) Find the magnitude (in pT) and direction of the net magnetic field at a point halfway between the wires. magnitude T direction into the page (b) Find the magnitude (in yT) and direction of the net magnetic field at point P1, 11.0 cm to the right of the wire on the right. magnitude direction рт out of the page (c) Find the magnitude (in yT) and direction of the net magnetic field at point P2, 2d = 22.0 cm to the left of the wire on the left. magnitude direction out of the page (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 pT) and direction of the net magnetic field at a point halfway between the wires. magnitude РТ direction no direction Find the magnitude (in UT) and direction of the net magnetic field at point P1, 11.0 cm to the right of the wire on the right. magnitude Грт direction out of the page X 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. Find the magnitude (in uT) and direction of the net magnetic field at point P2, 2d = 22.0 cm to the left of the wire on the left. magnitude РТ direction out of the page
