Hey guys!

Could anyone tell me how to make a really strong magnet at home? What things to use if its possible? Thx. I'd appreciate it. [:)]

You would have to try very hard to make the rare earth ones at home, near the bottom of this article it describes a couple of manufacturing processes

As far as I can work out you need a source of neodinium, iron and boron, a furnace to sinter things at 1000C  a set of mills that can grind very hard metals into powders, and an electromagnet that can apply a field of the order of a tesla...

Making a weak magnet is however quite easy - just sticking some iron to a strong magnet will do it, to get a better effect heat iron to red heat and allow to cool in a stong magnetic field.

try making an electro magnet much simpler but if a real magnet is what you desire then patience is the key get a lump of hardened iron and start tapping with a hammer always hit in the same direction up and down the lump with alot of time you can make a very very strong magnet
