1. The problem statement, all variables and given/known data 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? 2. Relevant equations 3. 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.
