Need help on this science project...?

Question

I'm just wondering, what would happen if,
i were to get four magnet bars, turn them over so they are they repell each other. Then put a small metal ball inbetween the four mangets. Would it float?
This was a idea i had for a science project.
Would this actually work. If not do you any other suggestions.

Answer 1

No. It would be unstable, actually being attracted to all four magnets and would end up touching one of them.
1. You could use ring magnets and put them on a stick in an opposing stack and show they stay evenly spaced (but closer together) as you apply pressure and you could measure the pressure or put measured weights on it.
2. Much more complicated: you could make an alternating current magnet that would induce a current in a non-magnetic metal disk (aluminum or copper) and the current makes a magnetic field which repels the first and the disk floats (mag lev trains, etc.)
3. You could mount the magnets on a box and make a slot way to guide travel and glue magnets down so they repel the box magnets and see if you could make a small magnetically suspended vehicle.

Answer 2

use the magnets to generate electricity .

make a flashlight.
