A long, straight wire carrying a current of I1 =5.0 A perpendicular to the xy plane (page on a table) intersects the x-axis at the origin and points +z direction (out of page). A second, long wire carrying I2 = 12 A intersects the x-axis at x= 6.0 cm and points -z direction (into the page). Find the direction and magnitude of the net magnetic field due to these two currents at (x=0, y= 8.0 cm). First draw a neat...

A long, straight wire carrying a 3 A current perpendicular to the xy-plane intersects the x-axis at x = −2 cm. Another straight wire carrying a 3 A current perpendicular to the xy-plane intersects the x-axis at x = 2 cm. At what point(s) along the x-axis is the magnetic field zero if the two currents are in the opposite direction? If there are no such points, write “None” and show your reasoning.
