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 couldn't 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.

You had #2 right the first time. Why did you change your answer?

To find the answer to the first question, about parallel metal conductors, you will need to apply the right-hand rule for parallel currents. According to the right-hand rule, if the currents in two parallel conductors are in the same direction, they actually attract each other. This is due to the magnetic field generated by the currents. When the currents are in the same direction, the magnetic fields produced around the conductors interact, creating a force of attraction between them.

As for the second question, the direction of the force acting on a current-carrying conductor lying in a magnetic field can be determined using the right-hand rule for magnetic forces. If you extend your right hand such that your thumb points in the direction of the current and your fingers point in the direction of the magnetic field, the force on the conductor will be perpendicular to both the current direction and the field direction. This means the force will be at a right angle to both the direction of the magnetic field and the direction of the current.
