The two wires shown in Figure P19.38 carry currents of 5.00 A in opposite directions and are separated by 10.0 cm. Find the direction and magnitude of the net magnetic field at the following locations.

Two circular loops of wire, each containing a single turn, have the same radius of 3.10 cm and a common center. The planes of the loops are perpendicular. Each carries a current of 2.10 A. What is the magnitude of the net magnetic field at the common center? Number i eTextbook and Modia Units +

Q8.2

The figure below shows two wires carrying currents of I = 5.30 A in opposite directions, separated by a distance d. Assume d = 9.6 cm. a).Find the magnitude (in µT) and direction of the net magnetic field at a point halfway between the wires. b).Find the magnitude (in µT) and direction of the net magnetic field at point P1, 9.6 cm to the right of the wire on the right. c).Find the magnitude (in µT) and direction of the net magnetic field at point P2, 2d = 19.2 cm to the left of the wire on the left.   d). What If? Repeat part (a) 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.
