  1. I’ve never seen a laptop that uses magnets for the lid, it’s always been a little switch. Something to look out for I guess.

    Did you just censor the word “fools”? Why the hell would you do that?

  2. ” Besides that, copper wires can have pointy ends and magnets can pinch you.” lol!!!

    @gd
    I’ve never lost data because of a magnet. I have tried so hard. at worse I was able to crash the heads.
    Why “Fools”? maybe he meant Fucks? Shit I got to watch my damn crappy language

  3. eclecticos: Rubbish. A static magnetic field shouldn’t have any effect on the metal detectors near traffic lights (and gate openers etc.)

    I used to have to go through a gate that didn’t detect bikes very well. Easily fixed by just laying the bike on the ground. Never had the same problem with traffic lights though.

  4. The static magnetic field moved through the inductor coil’s field can sometimes cause enough of a variance that it will trigger the light. You’ll need a rather large magnet though… not the kind they sell at hobby shops.

  5. All the dell inspiron’s use magnets to detect the screen being shut. the original black berry (RIM 957) used a magnet to detect the holster.

    about the traffic lights though it is off subject ill hit ever notice the broad spectrum of noise that is transmitted from the inductors. it fuzzes all the analog fm channels in my radio. Never tried AM.

    and now the reason i clicked comments. get a few magnetron magnets and play with your kids. they are strong enough to attract each other through most wooden tables. put on under the table and one on top. at the same time you can teach your kid how to avoid all those smashing expereiences you have had as a kid. they also work great for holding your little-ones masterpieces on the fridge.

  6. Magnets are cool and very useful

    I tried to use a magnet from a harddisk to retrieve my keys from a rain-gutter, but damn none of my keys were made from plain old iron.

    I also used these magnets to make a magnetic mountpoint for this small wireless camera which has to be moved around quite a lot.

    And finally I sometimes rub a screwdriver on one of the to make it a bit magnetic to retrieve screws from the intestines of machines.

    No real tricks, but still handy stuff

  7. Cool use is waving it around a harddisk so the uninformed people freak out.
    Or sell it as a medical magic thing to the slow-minded housewives and get rich quick :P

    Incidentally, I like that eddy current vid, it’s cool and also informative for people because theory is often too theoretical to be comprehended as a real thing in real life.

  8. if you swallow a small ferrite magnet, it will lodge in your small intestine and slowly dissolve, imbuing you with incredible magnetic powers.

    I bet that that’s not allowed here, too easy to sneakily change plates.
    Plus people could steal them too easy, or if we all did it swap them, in seconds.
    Not that I personally have a big issue.
