Northmount Posted June 19, 2012 Report Posted June 19, 2012 1340091620[/url]' post='253153']I was wondering though, I thought that magnets and computers etc. were not a good mix... The hype about magnets and computers is over stated and exaggerated. Floppy disks were supposed to be sensitive to magnets. I purposely tried to damage the data on floppy disks with magnets in various ways. No problems with reading data after. But electromagnets, especially powered by AC will destroy data on floppy disks and magnetic stripes. AC magnetic fields are used to bulk erase tapes and disks. Funny thing about floppy disks is that after a bulk erase, I couldn't reformat them. Memory chips in general are not affected by magnets. iPads and BlackBerry phones use magnets in the OEM covers and cases to turn the device screen off when the cover is closed or the phone is placed in the holster. Experiment with the covers and you will find out where the magnets are, and can then build that into your covers, just like the OEMs. Keep magnets away from the old CRT type monitors and TVs. Else you will have areas with poor color rendition, and have to have it degaussed to eliminate the residual magnetism around the screen. I have a BIG magnet out of an old hard drive. The drive was the size of a small automatic washing machine. I showed my kids how the magnet distorted the picture on our TV one day. Oops! The lower right quarter of the screen was now magenta colored. Had to rig up a degaussing coil to fix it. Kids learned a lot that day! CTG Quote
Members jana Posted June 20, 2012 Author Members Report Posted June 20, 2012 Yep. Only he answered better than I could. I am able to tell you that the Ipad is built to use the magnets to turn the pad on and off when the cover is opened and closed. It was an interesting project to figure out and construct.
