finnish?

@psp10004

Yap, how's that?

[foolphysics]

Your wearing a glove with the magnet. It must be quite extreme.  Are you worried iron is going to be pulled right out of your hand?

[AdminGoogolplexian]

Actually, yes. Hard drive is iron covered and if that magnet has strenght of 100 kg, I dont want to let my fingers between magnet and drive. It would be really painful to separate it.. Once I was eating with metallic fork and I didnt notice that magnet was nearby.. well, magnet flev towards fork and I had, of course, hand between.. ouch

That thing has a pulling strength of 100kg on iron... i'd understand if he had gloves on for safety :)

as for iron being pulled out of your body by a magnet; iirc that's impossible with that magnet, since your iron isn't affected by it (i think it has something to do with it being ionized)

[AdminGoogolplexian]

You are right about ionized iron, but theres small change of tattoo being pulled out due to large magnets (larger than mine, maybe MRI -magnets). On tattooes iron is not ionized...

Wow, but this HardDrive was Strong ^^

[AximKK92]

@TehMG either that, or it's just pulling on the paramagnetic metal of the platters so hard that the friction in the bearings starts to increase.

[TehMG]

Wow, the magnet is so strong it induces an electric current into the platters as they spin by, which produces an opposed magnetic field and causes them to slow down.

Gee.. so no difference in terms of stability with or without a magnet on the drive, impressive.

..and yes, I'm joking :P
