Experiment: Checking Biot-Savart's Law

AI Thread Summary
Biot-Savart's law can be experimentally checked by measuring the magnetic field strength around current-carrying wires and comparing it to theoretical predictions. While the law is derived from historical observations, its differential form cannot be directly tested, only inferred from the integral form. The integral form, established by Laplace, has been confirmed in specific cases but cannot be universally proven. The discussion highlights the challenges of validating the law with practical experiments, particularly regarding the limitations of wire thickness. Overall, the focus remains on understanding the experimental basis behind Biot-Savart's law rather than seeking a definitive proof.

how does one experimentally check biot-savart's law
 
Physics news on Phys.org
Maybe you could time travel back to the early 19th century when people actually cared?

Or you could enroll in a freshman physics laboratory class where no one cares about anything.
 
no isn't it imp...
well why i asked is it holds only for 'thin' wires and are the wires which we normally use sufficient to test it's validity
 
Why can't you just measure the magnetic field strength and see if it matches the theoretical calculations at that particular position?

Besides, like Coulomb's Law, isn't B-S law a phenomenological law historically? So it CAME out of experimental observations in the first place.

The differential form of the B-S law cannot be tested, but can only be inferred from the integral form. The integral form was first written down by Laplace, based on the experiments of B and S with closed circuits. Because of its general nature, it can only be confirmed for specific cases (always passing so far) but not "proven" in general.
 
thanks for that i just wanted to see the experiments behind it ...
and ofcourse not a 'proof'
 
Thread 'Question about pressure of a liquid'

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
