Will magnetic tank bags wipe iPod, mp3 music?

[swbarnett]

If you have iron balls it'll help you stay on your bike!

Well, blood has a high iron content so I suppose if one had an erection there might be enough iron in the genetal area for this to work.

I like to cover my helmet in tin-foil - it stops the aliens from sucking out my inner most thoughts - and trust me they are best kept in there.

As for my balls - they are welcome to suck them.......

Been using magnetic tank bags for years & shove all sorts of shit in it.. nothing has ever come to grief... although there was this one time....

I had my cell phone in the clear map bit up the top.. & it managed to slip out.. jus saw it out the corner of my eye luckily.. but was unable to catch it in time.. & it went bouncing off down the road in several pieces on the Lewis Pass.. only time my tank bag & cellphone have not agreed..

AND... bugger me.. I took the innards of the phone into a shop.. she put a new battery in it.. & sparked it into life.. new battery & plastic cover.. just like a new phone, for $50!!

How about a magnetic security card? I used to keep my credit card in my wallet beside one of these until it completely stopped working. I'm only assuming it was the magnet as there was nothing else anywhere near it except leather, cash and other cards.

Yeah, could've just been coincidence.

However, I've watched one or two of the Mythbuster episodes and, while a lot of what they do is probably scientifically sound, there were one or two experiments they did that were full of holes. I wouldn't necessarily trust their experimental design skills.

One thing I can say for sure is that 5.5" floppy disks (showing my age I know) don't like being magnetically attached to a metal noticeboard - totally erased it.

Which ones, and how so?

[mikeey01]

no, tankbags magnets wont affect ipods, cell phones, mp3 players, navmans, credit cards, or porno mags*.*Actually I can't back that up.

Mythbusters proved it takes a *very* strong magnet to wipe a credit card. Much stronge than any tank bag could ever put out..

Sorry but your incorrect!

A Magnetic tank bag can wipe a standard magnetic plastic card.. it's got to be close to the magnet though!
As for mp3's etc etc etc, nope you'll find they are shielded enough (or should be), i.e. inside and surrounded by a case / protection so they are not normally affected!

Credit cards, ATM / EFT-POS / bank cards, door entry cards, library cards that contain the dark magnetic strip commonly found on most cards have four tracks of data.
Any magnet source with some strength (a normal magnet, transformer field, speaker/s non shielded etc etc) can wipe or harm one if not all of the four magnetic tracks on a card, normally it's enough to kill it, however the most common is a partial wipe of data so it's un-readable or just contains meaningless characters / rubbish somewhere in the line on the affected track.

SMART cards: The smart chip is not affected by a magnetic field, electrons however do stuff them.

If I was you I wouldn't put any atm, eft-pos or credit card anywhere near a magnetic field.

You'd be okay to put anything in it so long as it was on your bike, but the moment the tank bag is taken off you/or it will close the magnetic flaps and if the card is close enough to them, o bugger!

Unfortunately I don't remember. I just remember thinking that they didn't know much about rigorous experimentation, and neither did my wife and she should know - Masters and past Lecturer in Physics.

A lot of what they do is probably fairly black and white i.e. it either works or it doesn't. But there will be some things that need more detailed investigation before any firm conclusions can be drawn.

and your point is?

[imdying]

Yes, a member here found his 2 week old ipod stuck to his tank bag magnets... that was it... kaput. I dare say it dragged the heads onto the platter and physically knackered it (i.e. it wasn't 'wiped' by the magnet). So yeah, a tank bag can most defnitely write off an ipod. Luckily, even though it was purchased overseas, Apple ponied up a replacement.

[prettybillie]

Fuck me, don't they teach physics at school anymore. Does anyone thats a beneficiary of modern education actually have even the slightest idea of how anything works ?

Obviously no - so are you going to tell us or what?

[samgab]

Just in case you don't fully trust that an ipod will be safe, you can use an iPod Nano, or Shuffle, or Touch; all of which use Solid State memory, which won't be affected even by very strong magnets.

I know of eftpos cards being ruined by being kept in a purse with a magnetic closure. But that is off-topic really, and I have no idea whether mp3s would be affected. The general consensus here seems to be "no".

i have been told somewhere that placing card strips together can affect them. i dont know how much proof there is to it, but im always careful to keep the strips away from each other.
