I calculated the x-int from the function values but the full plot looks like this: y-axis is in V, and x-axis is in m

When plotted to a custom fit, we obtain an equation of ##y = \sqrt{1.465x + 0.03263}##. This would suggest that if the magnet were to be dropped at ~2 cm below the top of the horizontal, no emf would be induced. However, for this plot we do notice a relatively poor RMSE value, but at the moment...

It is interesting, as just from some simple graphical analysis, it appears that the function of negative magnitude vs. height looks a lot closer to a ##y = \sqrt{x}## function than the positive magnitude. Using the experimental data, if we try to plot it as a power function on excel, the...

Hi, I am definitely still interested, as this is a project that I am still working on, just was quite busy over the weekend. It's going to take me a bit to digest the maths above but from what I have scanned I agree with you — I think emf should be proportional to the root of the height, as the...

Yes, I have been able to work out the bounds within which the emf is induced, however, I am struggling to figure out a relationship that directly related h, the height at which the magnet is dropped, and the rate of change of flux. To do this I would have to somehow fit the variable inside the...

I am currently working on an experiment that involves dropping a magnet from varying heights and measuring how the induced emf of a solenoid changes as a result. I am currently somewhat struggling with a derivation for a relationship between the two variables, however, this is what I have been...

I see - there is a lot to think about! Thanks a lot for the tips and I will refer back to this for further guidance in the experiment. I can see that I still have a bit of research to do! Thanks a lot

Thanks a lot! - I have attached a photo of a graph showing the change in voltage over time. You can see that the current reverses as the magnet passes through the halfway point and ∴ the velocity also reverses. However, I am simply looking at the magnitude of the Voltage, so what is really...

Looking at how the induced EMF is proportional to the rate of change of magnetic flux, intuitively it seems that if I increase the velocity of the magnet through the solenoid, i.e. drop it from a higher height, the EMF should increase as well. However, I am unsure if this is true and can't seem...

This is quite useful for the "applications of the physics concept", thanks a lot for the info!

Thanks for this, did you take this from a textbook or a paper? Would you be able to let me know the name? Thanks a lot! Edit: Never mind I can see the link to the paper.

As of now I have decided on doing a Wilberforce Pendulum, but this sounds really interesting so I might look into doing it for my other project that I will have to do. Thanks for the idea!

I ended up speaking to my teacher and we decided that a Wilberforce Pendulum would be a good topic to do. Thanks for the help!

This is actually a really good idea, I'll speak to my teacher about it. Thanks a lot! Edit: I'm also looking at a Wilberforce pendulum at the moment, which is looking quite promising and I'm just looking at the forumula's to see which variables I can plot.

Thanks a lot. I know that it's a really cool experiment which is why I wanted to do it, however the only thing is whether the analysis is far enough outside the scope of the course that we already do to give a high scoring extended essay. For example, we already do rate of change of magnetic...
