...or would the diamagnetic forces rip you apart first?

[TrashMan]

AFAIK, no.

In a strong enough EM field you could "float" - a.k.a. - simulate weighlesness.

I've seen experiments done with animals with no harmhull effects.

Weellll... a static magnetic field would not cause any induction whatsoever.

Also, technically a relatively small magnetic field can cause induction currents of substantial strength if it alternates powerfully enough, since induction voltage (which causes induced currents inside objects which conduct electricity) is related not only to the strength of the magnetic field but more on how much it changes and how fast [dB/dt or something like that, for the mathematically inclined]. So yes, in theory you "could" cause destructive inductive currents in any stuff that conducts electricity, with a rapidly alternating magnetic field.

...although in reality, making organic tissue to fry due to electric current without . Human tissue (including brain mass) actually conducts electricity fairly weakly, since there are almost no free electrons at all. Human tissue actually acts much like a saline solution, with all kinds of ions all over the place. Modeling how much voltage differentials an alternating magnetic field would cause in this tissue is not an easy task, and modeling how much actual current would be caused by the voltage differentials is another thing yet, because I have no idea what's the actual resistance of human tissue in relation to ionic current. So I have no idea actualyl how much magnetic field change would be needed for "frying" effect...

I can say from the top of my hat, though, that the magnetic field's rate of change would have to be very high, though, since MRI devices don't cause anything of any importance to living tissue, yet they can heat rings and anything metallic on your person to dangerous temperatures (not to mention the possibility of getting mauled by any piercing jewelry on your body). So I'm guessing that if the magnetic field's rate of change ever goes anywhere near the levels you're talking about, getting your brains fried would be the least of your worries.

I would guess that you would have much more success with generating micro waves with a directing parabola antenna and pointing it to the head of the person you wanna deep-fry. Just rip the magnetron off from a microwave oven, fit it onto the focus of a satellite antenna and you're set.

...of course, you might need a bit more power than the 750W from your household microwave. So you need to build a high-voltage, high-powered RF transmitter set on microwave frequencies. But then again you encounter the easiest and fastest (and, unsurprisingly, the least high-tech) way to fry your brain with electric interaction (also called electrocution).

Yeah, basicly a several righs arranged ina cylinder and those on the bottom had more strength, so anything you put in the "clynder" would be pushed up. By setting hte strenght right you could push smaller object up wiht enough constant forge to counter gravity. There was a funyn video when they put a frog inside the cylinder and it floated around.

Of course, if you suddenly GREATLY increased the power in a sudden impulse you'd end up with a coilgun and launch hte poor frog into orbit

I meant causing electric current in your nerves through magnetic induction, completely destroying your mind. "Fried" is the best I could put it. But is this actually possible?

[Mars]

Your nervous system isn't really a great conduit for induction, it's hard to induce a big current in something non-metallic like a neuron. If you had a really, really big magnet maybe, but you'd probably get killed by the other energies involved.

You don't have threads like these on most other game forums...

Exactly.

You need to understand that while nerves do transmit electric potentials from each other, it's not the same kind of electricity that flows in metallic conduits in form of free electrons. It's not actually current, because in nerves, there are practically no free electrons, instead there are different kinds of ions. And they don't move in a "nerve tube" from transmitter to receiver... instead the electrochemical reaction moves along the nerve corridor as a pulse, and when it gets to receiver neuron (or muscle cell system) it changes the potential there, which triggers next action.

And even if there were "currents" in nerves, you have to remember that ions are a *lot* heavier than electrons. Thus the same electric potential (induced by, say, magnetic field change) causes much less acceleration and thus much less current on ionic solution than it would cause on a conduit that has a lot of lightweight, free electrons to be moved about with relative ease (that's why they are conduits, by the way).

On the other hand, organic tissue does have certain resistance and certain conductivity, regardless what nerves themselves do... so I guess that with sufficient energy input anything is possible, but I'm not very sorry to say that brains are very unsusceptible to EMP effect of any kind, including induced currents. If you had anything metallic near you, it would explode in white-hot cloud of expanding vapourized plasma if the magnetic induction were at sufficiently high level to cause electric currents in organic tissue.


But remember also that you only need to rise the temperature of human tissue to about 45-50 degrees Celcius to literally fry it. Most proteins in human body start to coagulate at those temperatures, so microwaves would be pretty good death ray material, with sufficient power that is.

Imagine if you had an anti-magnet, that is, it repelled metal. That would be good for making your way through crowded cities.......imagine...........

Thanks, everyone! Science is fun! I'm glad I actually got a clear answer!

And my hopes of being one of the cooler James Bond villains are dashed forever...

Yup.... "Look Ma, I cna fly!"

[Herra Tohtori]

Yes, well, as I said, static magnetic field does not cause any induction whatsoever so clearly the question was not about what static magnetic fields do to living beings...
