My kids were playing with some cool magnetic rocks and left them sitting on top of our iPad. This provoked some non-trivial discussion in our family as to whether this was a bad thing.

I grew up in the era of magnetic floppy diskettes, where sitting a magnet on one could cause you to lose important data. But the iPad, as far as I can tell, doesn't have any magnetic storage. It clearly does have magnet sensors, as that's how the Smart Cover turns it off and on, and I'd hate for magnetic rocks to desensitize said sensors, but I'm also thinking that it seems unlikely that magnets will cause data loss.

What are the risks, if any, of leaving medium-strength magnets (not weak, but not any kind of industrial super-magnet), sitting on top of an iPad? Assume that the screen is covered, so I'm not worried about scratching the glass.

You should be fine. As you note, there are magnets (which are actually fairly strong for their size) in the iPad and Smart Cover. There are no magnetic components aside from the Smart Cover attachment points and the unlock sensor—there's a magnetometer for the compass, but it doesn't use a magnet.

Furthermore, the whole magnets damaging hard drives thing is a bit of a myth. You can wipe them with magnets, but it takes a very powerful one, pretty much nothing you'd have in your home.

    I know I've had floppy disks that worked, were exposed to ordinary household magnets, and then didn't work. I realize there's some risk of the whole post hoc ergo propter hoc fallacy, particularly because floppy disks didn't take a ton of prompting to go bad, but that's my experience. Never had any trouble along those lines with hard drives, though.

  • Yes, floppy disks are much more sensitive than hard drives to all sorts of issues, not just magnets. IIRC, with floppies the issue is more constant exposure to magnetic fields.

  • I would also add to your answer that magnets are only a real concern for Hard Drives. Hard Drives use magnetization to read and write data. Fortunately, iPads do not use HDD's. They use SSD's which are basically immunes from magnets. superuser.com/questions/338641/… Commented Apr 12, 2018 at 21:44

I have a case with magnets to keep it closed, haven't used iPad in over a month (magnets sitting on iPad without moving) now the entire top half of my screen has 100's of multi colored lines going across it and you can't see anything on the sop half but can still interact with it. At this point I will never trust magnets around electronics again.

  • Read up on 'post hoc ergo propter hoc' @Daniel mentioned in his comment to the other answer. I think this may be an instance of it.

I have 2 iPads - iPad3 and iPad Air. The iPad air has a magnetic cover from iHome. I placed the iPad3 (face down) on top of the magnetic cover of iPad air over night and now i can't power up my iPad 3. :(

However, the iPad Air is still fine with the magnetic cover but the magnet is on the back side of the iPad Air. So, I guess it really depends on where and how long you place the magnet on the iPad and it does and damage the battery. I am not going to use the magnetic cover on my iPad Air anymore.


Oddly enough I've done some reading on this and it seems a magnet, unless we are talking dangerously powerful, cannot erase or damage flash memory.

However, I had to return an iPad that had failed and was assured by the 'Genius Bar' that they put them through a powerful magnet to erase the data. When I mentioned that magnetism doesn’t erase flash memory the response was "I'm not sure but that’s what they tell us to say"


My iPad air just stopped working after being in my therapy bag with magnets(children's toys) for three days. There were not problems prior. If it wasn't the magnets it's a strange coincidence. Try it at your own risk!


I just picked up my iPad off a shelf and it was behind a speaker. Half the screen is damaged. Let this be proof magnets will damage your iPad mini.
