This is for a college assignment that is due in 2 weeks. I have tried searching everywhere for answers but nothing useful comes up. I want to understand how mechanisms inside a high-speed rail are able to cause the train to move. Any answers?
Hi Dave!
First of all, apologies for not making my statement a little bit more clearer. The experiment that I'm currently doing is measuring magnetic force with a basic current balance where the current is supposed to always stay at a constant 0.4 A. The thing is, it always fluctuate and I do...
Why is the reading on my D.C. ammeter fluctuating? As in the needle won't maintain at one spot, it'll sway left and right. Also, how do i ensure that the fluctuations are minimized?
Hi guys, so I'm having a little trouble completing my physics lab report here due to not being able to find many errors to discuss about. The experiment that I conducted makes use of a basic current balance:

As you all know...
