Answer
$B_1 = 20~mT$ into the page
$B_2 = 40~mT$ into the page
Work Step by Step
At point 1, the magnitude of the magnetic field is $20~mT$. By the right hand rule, the direction of this magnetic field is into the page.
At point 2, the current is flowing in one direction in one wire, and in the opposite direction in the other wire. However, the currents in the two wires are on the opposite sides of point 2. By the right hand rule, the magnetic fields produced by each wire will add together. Therefore, the magnetic field is $B_2 = 40~mT$. By the right hand rule, the direction of this magnetic field is into the page.
