Magnetic Screens?

I just discovered today that my MacBook Pro and my iMac are magnetic. Did you guys know this? My paper clip stuck to the iMac today, and that's when I noticed that all around the screen it is magnetized. My MacBook Pro is only magnetic on the top two corners from what I can tell.

I wonder if it's anything more than the mechanism that keeps the lid closed?
I experimented after reading your post and found that like yours, the top two corners of my MBP are magnetic.
I went to iFixIt to see if I could figure out the source of the magnetism, but I couldn't.
More: I just tested, and found that my palm rest is also magnetic.

Not with an iMac. No lid to close!

The magnetism on the edge of the MacBook screen, and on the iPad Pro screen, can easily be explained by Apple's long-time use of magnetic switches to turn devices off or put them to sleep when the lid is closed. But as Rita points out, that does not explain the magnetism on the iMac display.
On the theory the magnetism in the iMac is an artifact of the electronics in the display and since the closest thing I have to an iMac is my wife's 27" Apple Thunderbolt Display, I tested it with a paper clip and found magnetic “hot spots” every four or five inches around the entire display frame. Since it would place my life in jeopardy, I elected not to disassemble my wife's display, to absolutely verify my theory. But I am confident that had I disassembled the monitor would have found the magnetic “hot spots” correspond with electromagnetic coils or components of the display. NOTE: I did not find any corresponding magnetic “hot spots” on my more recent LG Ultra Fine or LG

I just discovered this about my iPad yesterday. Actually, I noticed that it wakes up when I pull back the cover of its case. I just tested it, and it will hold a “jumbo” paper clip when turned over.
