- Can security devices harm DVDs and electronic devices?
- Posted by curious@nospam.com on February 22nd, 2005
A few days ago I was at Best Buy and bought a couple of DVDs and a vacuum
cleaner. The security guy at the exit had this large handheld device, and he
rubbed it around my DVDs and then rubbed it on just one part of the box that
the vacuum cleaner was in. So he was either using the device to deactivate
any security tags on my DVDs and vacuum cleaner, or using the device to
determine if I was stealing anything. I guess the device outputted some sort
of magnetic field. My question is this: would a magnetic field be harmful to
either DVDs or electronic items such as vacuum cleaners?

DVD and CD disks are purely optical devices. You can run these through an
MRI, and they will still play very well.
The bottom line is a big NO for harming DVD's and CD disks with a magnetic
field.

But the magnetic field could also induce current in the vacuum's electronic
components... would that be harmful to the vacuum at all?

Ask the vacuum cleaner!

TVs and computer monitor screens can be damaged too. Degaussing will
usually fix it, but not always.

But keep magnetic fields away from the magnetic stripe on your bank/credit
cards!
One guy laid his credit card on top of a hardware store check out security
tag cancellation device and the card got 'wiped'!

Yeah I read that the magnetic field generated by an MRI could damage
electronic devices, so I was just wondering if it is possible that a weaker
one could also do some damage.
BTW, when you say "electric field", do you just mean static electricity?
