Can I use a regular magnet for a homopolar motor?

[Qube]

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.
