Eli5 : Modern electronics and magnets. How?

256 views

When I was growing up, you had to keep magnets away from computers and other electronics. Magnets could single-handedly wipe drive and disk, and could play havoc with cables transmitting data. It was generally taught to me that these two should not be mixed with, barring the proper housing. However, magnets are everywhere with modern electronics and computers and it’s something that has been quietly puzzling me for quite some time now. Please someone, explain how this can be. I know there is a very simple answer to it, but my brain can’t conceptualize it.

Magnets were only ever bad for very few technologies (CRT monitors, floppy disks, early hard drives) that are basically all obsolete now.
