I don't think magnets hurt the monitor it will warp it into many pretty colors but most moitors have a degauss feature that returns the monitor to an unmagnitized state. WARNING magnets hurt hard drives, floppy drives, vcr tapes and any other magnetic storage devices permanently. Don't get your 50 pound subwoofer around your computer.But the monitors with speakers mounted on the side are not going to break, the speakers are either so small they don't interfere with the electron tube in the monitor, or the speakers are magneticly shielded.
