I have been trying to come up with a good question for my Ib extended essay which is a 4000 words essay about any physics topic of my choice. However, with this topic I need to come up with an experiment to further investigate this topic and write up an analysis and conclusion. I am really interested in the topic magnetic force and relating to the concept of magnetic levitation trains. However, some of the topics I came up with were too easy and there is no depth to write about it later in the lab work. I was wondering if anyone can help me to come up with an experiment with a more complex relationship between variables for magnetic force? Thank you very much!

I've never seen anyone post an equation for the force between two dissimilar magnets.
Something like that?

I'm not saying that no one has done this, but only that I've never been able to find it.

And after a quick google, it seems I'm not alone:

Magnets Are Weird

The Dissimilar Magnet Calculator (not available)
What about magnets with two different sizes or shapes? How much will they attract or repel? How do you figure that out?

We always figured this would be a cool project: build a magnet calculator that would predict the force between two magnets that are not the same size. Every time we try attacking the problem, though, we find strange exceptions that make the task difficult. Magnets do weird things that aren’t easily described in a single pull force number. Magnets are weird.

Still no answer.
 
Thank you! that sounds like a interesting topic, I will confirm this with my advisor!

You'll either get an F, or become world famous.

Just kidding about the "F".

I've done lots of experiments with magnets.
Sometimes I learn something useful, and sometimes, weird questions pop up.

For instance, how do you weigh a magnet?
Magnets not only feel the pull of gravity, but are also pulled in the direction of the magnetic flux field of the Earth.
And the magnetic field of the Earth, as I discovered, didn't point in the direction I thought it did.

Anyways, good luck!
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
