Ferrofluid

Click For Summary

Ferrofluid can be made using iron filings, oil, and a binder. A basic recipe requires a suitable oil, such as olive oil, to suspend the iron filings. The binder is essential for maintaining the stability and viscosity of the ferrofluid. Options for binders include surfactants or specific polymers that can help achieve the desired properties. Proper experimentation and adjustments may be necessary to create an effective ferrofluid.

I have a box of iron fillings. Can I make a ferrofluid with this and if so what other things do I need?

just some oil to make a basic one, you also need a binder to make it like the ones you see in the ferrofluid sculpture vids:

would olive oil work? What kind of binder do i need?

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
