Final answer:
The magnetic field is zero at points 1 and 2.
Step-by-step explanation:
The magnetic field is zero at points 1 and 2.
To determine the points where the field is zero, we apply the right-hand rule. Since the two wires carry currents in the same direction, the magnetic fields produced by each wire cancel each other out at certain points along the lines connecting the wires. In this case, points 1 and 2 are located on those lines and experience zero magnetic field.
