Magnets near the new M1 pros?

I remember a time when magnets near any tv / monitor / hd etc was a huge NO NO, is that still the case for these new laptops? Considering iPhone has a pretty sizable magnet built it…

TechMatte Magnetic Laptop Phone Holder Computer Monitor Expansion Bracket, Adjustable Laptop Extender Side Mount Compatible with iPhone 13 & iPhone 12 Series MagSafe Case https://smile.amazon.com/dp/B08YR1BMLW/ref=cm_sw_r_cp_api_glt_fabc_2Z4AFAPJ78FG47HFZH4S

Was thinking of picking one of these up but of course don’t want to do any potential damage to the laptop

There is nothing inside that would be damaged by a magnet. Magnets were only ever a threat to magnetic data storage devices, such as hard drives. TVs were never at any risk, though a magnet could affect the picture.

Magnets can interfere with the sensors that tell when the lid is closed or open. I tried a third-party MagSafe-type connector that interfered with sleep when the lid was closed. Depends on where you put the magnets. The setup you linked to would probably be OK as long you remove it when you close the lid.

I'm positive that magnets will have almost no negative impact on your laptop ;)
 
Conventional HDs, along with cassette tapes and other tape recordings, use a magnetic medium to store the data. Magnets can wreck havoc on those, aka magnets are used as "bulk erasers" for old time magnetic media. CRT type monitors and TVs use magnets to "steer" the electron beams so an external magnet will seriously mess up the display. If the magnet permanently magnetizes part of the CRT then it can be ruined.

None of this applies to modern LCD screens and SSD storage. The magnetic flux in a MagSafe charger on your iPhone provides a magnetic field and no damage to the components of the phone.
 
Only for the sake of useless information. Sliding my iPhone SE across the left speaker of my 09 MBP, temporarily sleeps the laptop screen.

affecting the picture would be a risk no?

CRT TV screens only. Not LCD/LED/OLED/etc. And they will only affect a CRT picture while the magnet is in proximity. Once removed, the picture would be restored with no lasting effects.

As far as magnets and modern computers are concerned, there is no danger of damage; unless we are talking about EXTREME magnetic fields, as in don't put one in an MRI machine, or anything else that has extremely strong, fast changing magnetic fields.

So basically don't do anything ridiculously dumb, like put your laptop on an induction hotplate, or do an MRI on it if a spider crawls inside the air-vent, and you'll be fine.
