As always, it's only a question of budget (those "rare earth" permanent magnets cost a fortune!!!   )

Yeah, I know they're not cheap. A friend at work was building a windmill, we pulled earth magnets out of defective computer hard drives we were throwing out!
I ended up replacing all my fridge magnet's ceramics for earth. I know, I should have better things to do.

Hope your house doesn't have any steel beams in it; You'll find your fridge stuck on the sealing one of these days!

Boy, those magnets are good!

BTW The rare-earth magnets I have to use for my motor are about 20 cm long by 7 wide.  It's not a joke, you can really lift a fridge with two or three of those!  A friend of mine once (very stupidly) stuck a finger between two of those magnets and he have to go to the hospital for a fracture.  He crush a phalanx.
 

He managed to take out an entire Greek spear formation with a couple magnets?  Those are powerfull...







Sorry, it was the first thing that popped into my head.   

Wow!  Historic antiquity jokes!

And they say motorheads guy don't have sophistication and culture!!! 

OK, I was not shure about the translation.  In french "phallange" is the term for the bones inside the knuckle.  IS "phallanx" a correct translation or not?

D'uh!!! 

(Is it me or have we all a slight tendancy to go more and more off-topic around here?) 

Just looked, it is the same spelling.    http://en.wikipedia.org/wiki/Phalanx

As for off-topic, I think that is my fault half the time.  Work makes the mind wander.
