    Homopolar Magnet
AI Thread Summary
To build a homopolar motor in one week, a magnet is essential, and while neodymium magnets are recommended for their strength, other types may work. Amazon is a viable source for purchasing these magnets. The screw used in the construction should ideally be ferromagnetic to ensure proper functionality. Tips from experienced builders suggest that while creating a homopolar motor can be challenging, it is a valuable learning experience compared to simply buying a motor. Overall, understanding the principles behind motor construction, such as Faraday's law, can enhance the building process.

I have 1 week to build a motor.

I'm looking at building a homopolar motor.

I know I need a magnet. But does it have to be a neodymium one? And is Amazon a good place for such magnets?

And does the screw have to be a ferromagnetic one?

And if anyone has built such a motor, some hints and tips would be appreciated :D!

I don't really know much about building motors because it's crazy to build one when you can buy whichever one you need. So I guess my really only useful commentary is that you may be able to make a DC motor a lot easier, it's a classic because of the application to faraday's law.

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...
