Do magnets damage digital cameras or iPod nanos in any way?

I just bought an HP Photosmart digital camera today from Best Buy, and also bought a magnetic HP camera case with it. (so instead of velcro or clasps to seal the case, a magnet is used.) I know it’s unlikely, but I was just wondering if the magnets from the case would damage the camera or cause it to malfunction.

My iPod nano is about a year old now, and I’ve dropped it heavily two times before by accident. The first time, the iPod’s screen blanked out so that you couldn’t see anything on it. [if you touched the dial, the screen would light up like normal, but nothing would show on it.] You could still hear the music, adjust the volume, pick songs, etc, but you just couldn’t see anything.
When I dropped it a second time, the screen fixed itself and everything was normal again.

After that, I bought a magnetic nano case that flipped vertically like a cell phone with a magnet, and the day after I put the iPod in it, it blanked out. I didn’t drop it, so is it b/c of the magnet?

Short answer: No, magnets hurt neither ipod nanos nor digital cameras. Since your ipod nano has flash memory, and an LCD, it shouldn’t be affected by magnets.

Explanation of what probably happened to your ipod:

I’ve taken apart an ipod before (don’t worry, it was already broken, and I took it apart to fix it). Most likely, the first time you dropped it, the connector between the ipod and the screen was damaged (it’s a really really thin ribbon cable). The second time you dropped it, the connector was jarred back into place. Here are the questions you need to ask yourself to figure out what’s wrong:
1) Is music still playing?
*If yes, it’s a problem with your screen connector.
*If no, it’s a more serious problem.
2) Is the nano still under warranty?
*If yes, call up apple and have them send you a new one, or take it to an apple store if you have one nearby.
*If no, try dropping it again and see if it’s fixed.

Why magnets won’t hurt nanos:
The problem with magnets near things like computers lies mainly with erasing your data, and with damaging your monitor.
A) Monitor: Magnets will only damage your monitor if it’s a CRT (cathode ray tube) monitor–one of those big honking ones nobody uses anymore. That’s because it uses the path of electrons to make the display, and magnetic fields make electrons move in a strange way. If you press a magnet to a monitor long enough, the parts inside it will become semi-permanently magnetized, so electrons will be bending constantly, leading to weird colors and a blurred image. Now we have LCD (liquid crystal display) monitors which aren’t affected by magnets at all. Your ipod nano has that type of screen.
2)Hard Drive: Hard disk drives are composed of a magnetic head and a disk of ferromagnetic material (meaning it can be semi-permanently magnetized). The magnetic head will scan across the disk and turn its magnetic field on and off at certain times in order to magnetize small bits of the ferromagnetic material. This leads to some bits of the material being aligned one way and others a different way, leading to the binary system of 1s and 0s to store data. Clearly, if you put a magnet on such a disk, it would mess up the alignment of the material, and erase your data. New solid state drives use solid state memory/flash memory to store data. I’m not 100% familiar with how it works (although I studied it in nanophysics, so I should remember :(), but it has to do with logic gates. It’s not affected by magnets at all, as it uses an entirely different mechanism to save data. It also has no moving parts, which is why it can be so much smaller and last longer. It can also be dropped without damaging your data.
