1)When the currents in two parallel metal conductors are in the same direction, the conductors ___ each other.

A)attract
B)repel
C)do not exert any force
D)exert forces that are perpendicular to

I got A. I couldnt find where it talks about directions of parallel metal conductors

2)What is the direction of the force acting on a current-carrying conductor lying in a magnetic field?

it is at right angles to both the direction of the magnetic field and the direction of the current.

So #1 is attract and #2 is: it is in a direction opposite to the direction of the magnetic field.
