Dependency between force F and length L (Magnetic Field)

[superjose]

Homework Statement

Verify the possible dependency between force F and Length L of the conductor. For this, you will put six different plates, each one with different length from the conductor. You need to verify that by measuring F forces exerted by the magnetic field B, maintaining the same circulant current i. We can do the experiment by giving i a value of 3.0 A.

Graph the results, what conclusions can you obtain from it?

Homework Equations

The Attempt at a Solution

Since this is a theoretical question, I'd say that the force exerted by the magnetic field is directly proportional to the applied intensity and the length of the conductor.

Is this correct? I have my doubts...

I'll leave the graph below. Please note that this was made without very precise instruments (scale of 0.01cm precision). The point of the experiment was to use a magnetic plate in which I would have injected some current (3.0 A in this case) with an external power supply.

I would then measure the force F with a spring scale.From the graph, we can see that as the length of the conductor increases, the force F also increases. This indicates that there is a direct relationship between Force F and Length L of the conductor. Thus, we can conclude that the force exerted by the magnetic field is indeed directly proportional to the applied intensity and the length of the conductor.
