Homework Statement
In a lab I passed a magnet through a coil and measured the voltage.
I need/want to know why when moving a magnet through a coil you induce a current. I don't necessarily need a direct answer - I more just want to know if my argument holds and where to look if I'm completely off the mark. Note I am only dealing with classical physics.
I'm pretty ok with data. I managed to measure within the error bound what I was trying to.
Homework Equations
F = qv x B
The Attempt at a Solution
Ok, my theory relies mainly on the equation F = qv x B. I argue (in more detail) that as you pass a magnet through a coil, charged particles in the coil move with a velocity relative to the magnetic field. The edge effects of the magnetic field cause the charged particles to move in direction of the right hand rule, which induces a current and sets up a Voltage which is what I measured.
If this works then I'm happy with the rest of my theory. Due to a strange Summer Session timetable and me going on holidays last week I haven't actually learned much about magnetic fields and we will be starting induction tomorrow. I hate to put it to the internet for help but I've got no where else, sorry.
Thanks for any help.
