A long, straight wire carrying a current I1 is placed on a horizontal table in front of you and the direction of the current points +x axis. The magnetic field produced by the current I1 at a point 5 cm above the wire is 0.2 T. A second parallel wire carrying a current I2 = 3I1 is placed 10 cm above the first wire and the direction of the current also points +x axis. What is the direction of the net magnetic field produced these two currents at a point 5 cm above the table?

clockwise

counterclockwise

toward to you

out of page (table)

into the page (table)n

away from you
