F/l is the force per unit length between two parallel currents I1 and I2 separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and plasmas.

When a conductor carries current it emits magnetic field around it . By the right-hand rule, a current out of the page in a field up gives a force to the left. Two parallel wires carrying currents in the same direction attract one another; wires with currents going in opposite directions repel.

Explanation:
When two parallel conductors carry the same amount of current in the same direction, they create magnetic fields around them. These magnetic fields interact with each other and produce a force between the two conductors.
1. The Direction of Magnetic Fields:
When current flows through a conductor, a magnetic field is created around it according to the right-hand rule. For parallel conductors, the magnetic fields produced by the currents in both conductors have the same direction.
2. Force between Parallel Conductors:
The magnetic fields produced by the current in one conductor interact with the magnetic fields produced by the current in the other conductor. According to the Ampere's law and the right-hand rule, these magnetic fields exert a force on each other.
3. Attraction:
When two parallel conductors carry currents in the same direction, their magnetic fields attract each other. This is because the magnetic field lines produced by one conductor align with the magnetic field lines produced by the other conductor. As a result, the conductors are pulled towards each other.
4. Repulsion:
On the other hand, when two parallel conductors carry currents in opposite directions, their magnetic fields repel each other. This is because the magnetic field lines produced by one conductor oppose and cancel out the magnetic field lines produced by the other conductor. As a result, the conductors push away from each other.
Conclusion:
In the given scenario, where the same amount of current flows in the same direction along two parallel conductors, the conductors attract each other. This is due to the alignment of the magnetic fields produced by the currents in both conductors. The attractive force between the conductors is a result of this magnetic interaction.
Additional Note:
If the distance between the two parallel conductors is increased, the force of attraction decreases. Similarly, if the current flowing through the conductors is increased, the force of attraction also increases.
