Question

A transmission wire oriented parallel to the x-axis carries a current of   200 A   flowing along the +x direction. A second transmission wire also oriented parallel to the x-axis but lying at a perpendicular distance of   1.25 m   below the first wire carries a current of   250 A flowing along the +x direction. What is the magnitude of the total magnetic field at a point midway between the two wires?

Express your answer to three significant figures and include the appropriate units.

A transmission wire oriented parallel to the y-axis carries a current of   200 A    flowing along the +y direction. A second transmission wire also oriented parallel to the y-axis but lying at a perpendicular distance of   1.25 m    below the first wire carries a current of   250 A    flowing along the +y direction. What is the magnitude of the total magnetic field at a point   2.10 m   directly below a point midway between the two wires?

Part E

A transmission wire oriented parallel to the y-axis carries a current of   200 A    flowing along the +y direction. A second transmission wire also oriented parallel to the y-axis but lying at a perpendicular distance of   1.25 m    below the first wire carries a current of   250 A     flowing along the +y direction. If the location where the net magnetic field is zero is at perpendicular distance  d from the first wire, what is d ?

Part F

A transmission wire oriented parallel to the z-axis carries a current of   200 A    flowing along the +z direction; the wire passes through the point (4.20 m, 0 m, 0 m) on the x-axis. A second transmission wire also oriented parallel to the z-axis carries a current of   250 A    flowing along the -z direction; the wire passes through the point (0 m, 4.10 m, 0 m) on the y-axis. What is the magnitude of the total magnetic field at the origin?
