Two wires are oriented in free space as shown. Wire A is parallel to the z-axis and carries 2 mA of current flowing in the positive z-direction. Wire B is parallel to 5 the y-axis and carries 3 mA of current flowing in the pos- itive y-direction. The wires are 10 cm apart at their clos- est point. N 4 X 2 mA A 10 cm o Totoulinos B 3 mA Most nearly, what is the magnetic field strength halfway between the wires at the point where they are closest?
