The same amount of current Iis flowing through two wires, labeled 1 and 2 in the figure, in thedirections indicated by the arrows. In this problem you willdetermine the direction of the net magnetic field B_net_vec at each of the indicated points (A - C).

Q: What is the direction of the magnetic field B_net_vec at point A? Recall that the currents in the two wireshave equal magnitudes.
B_net_vec points out of the screen at A.
B_net_vec points into the screen at A.
B_net_vec points neither out of nor into the screen and \vec B_{\rm net} \neq 0 at A.
\vec B_{\rm net} = 0 at A.
---- the last one was wrong...
now out of 3...
