exactly

there’s magnetic, then there’s magnetic
I have a theory that the expansion of the universe is actually due to massive magnetic fields caused by various types of black holes. Vast amounts of matter spinning near the speed of light spiraling toward a singularity. Not necessarily antimatter. So there’s that level of magnetic too. Here is a good video explaining why the CT is magnetic. It has to do with work hardening the stainless and it’s crystalline structure Link

We tested the Cybertruck body for magnetism a while ago
We are looking at creating … possible clips to prevent wind from lifting the corners up and blowing off the panels at higher speeds.
I take it the magnetism tests weren’t exactly off the charts?

separately, a few Q’s about these magnet wraps:

I assume they’re not the size of entire panels? (The normal sized magnetic signs for autos, just the rectangle, are weighty, so I have a hard time imagining one the size of a door much less the rear QPs.)

How do they handle the various curved panels? (While the CT panels appear to be flat planes, many have varying degrees of curvature.)


Lastly, less of a question and more of a statement: I’d get the right disclaimer language for your product causing potential staining of the SS

I do not find it that surprising that the CT is somewhat magnetic.

I would instead find it surprising if it is strongly magnetic - not so much for the magnet stuff, but for the implications for staining, corrosion, etc.

The more magnetism, the more prone to staining and corrosion.

Ummmm.... no offense all... (and Happy Holidays / Merry XMas)... but...

It's stainless steel. Doesn't matter what alloy. It's steel. By definition it has iron and iron is magnetic. Who had any doubts about this that thought it through for half a second?

Confused about the confusion here... or am I missing something?

you’re missing that not all iron is magnetic

and that as a result a lot stainless steel, especially 300-series, is not magnetic (unless it’s been sufficiently temp or work-hardened)

I’d guess that a majority of consumer ‘stainless’ products are not magnetic. This is ~because most consumer stainless products are looking for the anti-corrosive/anti-staining qualities of the steel.

My stainless steel hot tub is not magnetic, my stainless cooking pans, refrigerator, dishwasher, etc., are all non-magnetic.

Stainless steels are roughly 75% iron, but that doesn't necessarily make them magnetic. "All stainless steel metals are a type of steel. That means their chemical composition contains iron. In most cases, stainless steel varieties with iron in their composition are magnetic. If the alloy has an austenitic crystal structure, then it's not magnetic."

There is both magnetic and non-magnetic stainless steel, and some none magnetic steel becomes magnetic when its worked (bent, cut etc).

So although stainless is predominantly iron, it's magnetic properties depend on its atomic structural geometry, which can change after being worked, whereas corrosion resistance comes primarily through the protection of added chromium and sometimes molybdenum, that forms a protective oxidisation layer over the iron.

Although, more magnetic stainless seems to more commonly stain, this is not directly due to magnetism, rather that this grade of stainless steel (304,409 etc) has less chromium.

So because this is a custom HFS Tesla blend of 30x stainless steel (x being an unknown variable) that was also apparently co-developed for Starship to bring the cost of the material down through mass producing it with CTs, we haven't yet found out all of the particular blend of its properties.

Ignore particles and matter. Just go feilds all the way, makes more sense and is easier to understand. Every particle interaction, "could" just be a feild interaction. The main problem actually becomes using the correct terminology to describe these, and avoid the negative connotations high school science gives labels like aether. N.Tesla made some fundamental breakthroughs many have either ignored or misunderstood.

Stainless steel, even though not fingerprint resistant, is more resilient to staining than a clear coat or standard pained surface.
sure, more resistant, but not ‘proof’

but the corollary here, is that when it *does* stain, it is a good bit more difficult to remedy than with a clear coat/paint.


Meanwhile, it’s the cleanliness and properties of the magnet material in your product that may be the most likelyculprit of any possible staining. Moisture (or oils, etc.) WILL get trapped between the vehicle and the product, and seep in at the seams, etc.

For typical vehicle signage applications, THEIR care instructions typically instruct that the magnets be removed DAILY in order to not cause paint staining/decay from either the car or the magnet corroding.

Granted, the CT’s stainless shouldn’t be quite this finicky - but if left on for months on end?

Just like one may have to resurface a clear coat/painted door, one may have to resurface the stainless. Neither pleasant jobs, if seeking a clean and uniform outcome.




None of which is to poo-poo an otherwise interesting sounding product. Instead to - unsolicited - look around a key corner of product marketing/liability.

there’s a reason other door signage manufacturers recommend removing theirs daily - people who don’t, can’t blame the manufacturer (or their online reviews have less teeth)

Absolutely! Hoping to do a Family Truckster edition, too!

This would be hilarious. I'm not convinced it will be possible, but if you get it to work that would be so funny.

Sorry, I don't think it will be able to be done in a cost effective and available fashion. You'll need multiple guides for getting the fit right, some dumbo is going to not attach it right and lose it on the highway, etc. it's definitely an uphill battle, but maybe you have the finances and the grit to do it.

Here’s a video of a powerful rare-earth magnet on my DeLorean.





The magnet adheres strongly to the latch and screws, but slides right off the stainless.
