Two parallel wires have electrical current running through them in opposite directions.
Which statement describes the force between the two wires?
A. There are no electric or magnetic forces on the wires.
B. There is a magnetic force pulling the wires toward one another.
C. There is an electric force pulling the wires toward one another.
D. There is a magnetic force pushing the wires away from one another.

Respuesta :

Answer:

D. There is a magnetic force pushing the wires away from one another.

Explanation:

When electric current flows through one wire then it will induce magnetic field now this magnetic field will exert the force on another current carrying wire

Now we know that force between two current carrying wires is given as

[tex]F = \frac{\mu_o I_1I_2 L}{2\pi d}[/tex]

so here if two wire have current in same direction then two wires will attract each other

Also when current in wire is anti parallel to each other then the force between two wires is repulsive force

so correct answer will be

D. There is a magnetic force pushing the wires away from one another.
