Homework Statement
Hello i just have an interesting question, and was wondering if my answer to it had any validity.Ok so i did an experiment The Current balance experiment(for everyone not familiar with it, you can google it and get all the info you want) to try and estimate mu naught. Anyways AC current was used in the experiment so transformers could be used to adjust the voltage applied to the circuit. So the question was why else was AC current used rather than DC. My answer to this question is, could this be due to the fact that the Earth has a magnetic field that will effect the experiment because the of the hall affect. Which is when charge carriers of a current carrying conductor experience a sideways Lorentz force due to Earth's magnetic field which results in a charge separation in a direction perpendicular to the current and to the magnetic field. So will this affect DC current because it only flows in one direction, but since AC flows in both directions will it somehow cancel out the Lorentz force?
