# Is it possible to induce prions/protein-folding diseases via a magnetic field of sufficient strength?

This logbook entry from Destiny 2 states that

WARNING. Novel prion detected in body collagen. Hypothesis: Jovian magnetosphere promotes highly abnormal protein folding. Prognosis: massive sloughing/fraying of basement membranes, Loss of tissue binding, inhibited durotaxis of new cells, delamination of all body tissues into thin sheets. You will fall apart Like an old book.

In other words, Jupiter's magnetic field is causing the body to misfold proteins, resulting in what sounds like an even-nastier-than-normal prion disease - in other words, a misfolded protein that turns other proteins into misfolded proteins. Imagine a zombie apocalypse, but with the building blocks of your body.

While I'm unsure as to whether Jupiter's magnetic field is strong enough to do something like this, I am interested in the concept. Is it possible for a magnetic field to cause proteins to misfold in a way that makes those misfolded proteins capable of misfolding other proteins?

• No. Almost any chemical interaction will be vastly more likely to result in abnormal protein folding, and I've never heard of anyone getting a prion from drinking coffee (for example). MAYBE if there were large metallic cofactors. Dec 3 '21 at 2:17
• On further review, forget about cofactors. Just no. Dec 3 '21 at 3:54

YT How Much Power Does Magneto Need to Rip Iron from Blood? - pretty entertaining to watch without sacrificing science

Fun fact, mentioned in the clip, moving inside the 7T field of a RMI makes you taste metal (by creating currents in your body strong enough to excite the nerves). Remember kids, if you ever wake up inside an MRI machine that you don't want to be in, moooove awaaaaay sloooowly!

"Human blood and human tissues is in the $$-10^{-6}$$ to $$10^{-6}$$ magnetic susceptibility" - that is, ignorable weak. So weak that, before any effects of the magnetic field start to manifest on the protein (and their folding), you will get intensities of the magnetic field that will make the actual chemistry of the elements in your body impossible (by modifying the shape and the energy of the electron shells)

Probably it won't do harm.. at least not very quickly.. a few years ago some mad scientist won the IG Nobel for physics with levitation experiments in a magnetic field. The field applied was a lot stronger than Jupiter's, which is about 470 micro tesla at the equator. It took 16 Tesla's (!) to lift a live frog.. it survived the experiment,
