Will magnets harm my electronics?

Maybe…The strong magnetic fields of these magnets can damage certain magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes or other such devices.  They can also damage televisions, VCRs, computer monitors and other CRT displays. Never place neodymium magnets near any of these appliances.  As for other electronics such as cell phones, iPods, flash drives, calculators and similar devices that do not contain magnetic storage media, probably not, but it is best to err on the safe side and try to avoid close contact between neo magnets and electronics.
