Hacking Magnet Strength for NTRBootHax

[sansnumen]

Hello. Now that NTRBootHax is out, all 3DS systems can be hacked in perpetuity (probably). But what concerns me is the use of a magnet to perform the hack on clamshell 3DS systems. Has anyone suggested which magnets would be appropriate for such a task? If I were to guess, the way the 3DS goes to sleep is by inducing a current flow on a chip near the face buttons. This can be done by using a current flow to induce a magnetic field on the right speaker and getting the magnetic field close enough to the face buttons.

It is quite possible to blowout the circuitry/chip near the face buttons by using a strong enough magnet. So again, that's why I ask, which magnets would be safe to use for NTRBootHax?

I've had success with every magnet I've tried that wasn't paper-thin. So, feel free to start small.

Obviously don't use big magnets. A simple fridge magnet will do the trick

Do you actually have an example of this happening though?
Seems like you would need some sort of rare and expensive industrial strength magnet for this to be a possibility.

You can use a 1 tesla magnet just fine if you bring it to the console slowly... induction depends on the variation of magnetic field, not on the total intensity
(Of course it may rip the top screen off the bottom shell )

The opposite is true of reed switches, which are actually controlled by the presence or not of magnetic fields (compare to a relay without the electromagnet, just 2 metal bars, one fixed and one that swings around, that can be pushed or pulled by external force

I have no examples, but I have seen people putting their systems to sleep by stacking 3DS.

I have fridge magnets. Should be safe. Although my DS Lite is dead so I can't test this. My 3DS is still on sysNAND 9.0 so I don't need magnets per se. This is more an academic exercise.

Yep what you say is true. I still remember from my college level E&M Physics class. Still 1 tesla magnet is super strong. You can bork other components on a 3DS without even trying.
