ugh you type worse than I do lol
its a good idea but you'll get better results with a balloon on a string placed in front of the camera or lasers

| | | | I was working in the vicinity of a very powerful experimental electro magnet, Not only did it lift and pull a crowbar I was carrying, but it wiped out all my credit card mag strips, and it killed my watch battery as well. All of this was from 30 feet away, and I was on the outside of the building it was in. Very expensive lesson.

But then I've had [MAXTOR] rare-earth hard drive magnets in the pocket next to my leather wallet with cards and magna-swipe IDs - no problem. I think demagnetization happens muuuuch more easily with powerful alternating fields - electromagnets or spinning regular ones is the only way. A tape or hard drive eraser involves a magnetic field to alternate between strong North and none and strong South several times, decreasing in amplitude - for a hard drive it has to be fiercely strong to reach inside the disk's case.

We all had ostriches. My dad had an ostrich farm! I remember one day someone came in and said the high altitude bombing of Kosovo had been a limited success, so we all went out and celebrated… by killing an ostrich and boiling it in kiwi fruit. |

Yeah, modern hard drives need an extremely strong magnetic field to bother them. I once put a couple of very strong hard drive magnets (from 15k SCSI drives) right on the case of another drive I didn't care about. Ran a continuous test for a couple of days and it was fine. That drive still works today. I keep a collection of hard drive magnets on my case at work with no ill effects.

| | | | I don't know enough about magnets, other than they are cool to play with. This one that wiped out all my info and batteries was an experimental MRI, one of the largest in the country, we stacked 7 nails head to toe on top of one another on the outside wall of this building. And the crow bar I was holding was very difficult to turn, felt like a gyro effect. They had us sign waivers, and they had to turn it down so we could work in th vicinity, they said if it was powered up higher we would not be able to hold on to our tools, the building could be damaged or some body injured or killed...
108 minutes, I had to dig deep to catch that one!!!

In a strong enough alternating magnetic field, you can induce current in -all- conductors, making them -all- electromagnets attracted to the MRI. That'd be an AMAZING implosion ;)

| | | | interesting. but im still pretty sure a tape eraser will destroy a harddrive as strong as it was. probubly would do the same if it touched a camera.
but i wouldnt want to destroy it. just interfere a bit to get past.
there are 2 types of security camreas we urban explorers have to worry about.
the kind that are recorded. and the kind that are being watched by a guard.
now you could cover a recording camera just fine. balloon or whatever you wish. but if its being watched thats a different story. you want to make it look like a glitch so you dont have a run in with the guard.

I'm not so sure a tape eraser would work on a hard drive. The magnetic particles in a hard drive are extremely strong, far stronger than a VHS tape. A decent VHS eraser (probably far stronger than your rat-shack one) has a max gauss of 1800. Bulk erasers for hard drives have gauss ratings of 6600 to 13000. 1800 gauss might damage a hard drive given enough time, but it would be far from a sure thing.
Also I'm with turbo on the camera. I don't see how a strong magnetic field would screw with a modern ccd camera, except maybe the power supply. An old camera with a magnetically deflected imager is more likely to be affected buy the bulk eraser. What kind of camera did you test it on?

| | | | i havnt tested it on a camera. but i wish to.
my co worker says it would most likely damage the cameras imaging chip.
and as for a harddrive im pretty sure it wont erase it as much as it will just tear it up from the inside out.
