In physics, a force is an effect that can alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. Intuitively, the force can be described as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

To get the force between the two wires, we will use the equation

$\mathrm{F}=\frac{{\mathrm{渭}}_0{\mathrm{l}}_1{\mathrm{l}}_2\mathrm{l}}{2\mathrm{蟺谤}}$

...................................(1)

and as the direction of the current in the wires are in opposite direction, the force between them will be repulsive.

Using the equation (1), we will determine the force such that,

localid="1654229999479">F=渭0l1l2L2蟺谤=(4蟺脳10-7N/Az)脳(800A)脳(800A)脳(50m)2蟺脳0.75m=8.53N

Therefore, the Force between the two wires is${}^{8.53\mathrm{N}}$

As the force is repulsive, this will prevent the two wires from touching each other and creating a short circuit.
