Homework Statement
Using a galvanometer and a coil, we thrust a magnet with a defined north and south pole into the coil and the galvanometer measured the induced current created. Now, depending on how the coil flow(front to back or vice versa) the galvanometer measured an induced current. However, when the magnet reached the end of the coil, it read 0. Why did this happen?
Homework Equations
- ε=-dΦ/dt
- I=Δq/Δt
The Attempt at a Solution
I can't seem to understand why the galvanometer would read 0. Because when the magnet is going into the coil, North side going in, it started changing, but once it reached the bottom it read zero. I keep thinking it has something to do with movement, but I am 99% sure that is incorrect. Can anyone assist me in my confusion?
