how does one experimentally check biot-savart's law
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'
