Will a strong magnet damage an MD?

Stew,

"Welcome to Friendly" my guess would be no, but wait till you hear from others before doing it. I can say keep it out of your wallet, it can raise havoc with the Master card.......Gil

I have some experience with these magnets as I alluded to in another thread somewhere in here. I wouldnt get them near your detector. I couldnt say with certainty that it would ruin it, but I bet there is something somewhere on your machine that would be damaged. The first thing that comes to mind is any type of display screen if you have one. Headphones, since they have magnets are almost guaranteed to be damaged.

I have seen a large one of these cause a TV to go wonky from 8 feet away. If I were to carry a big one in the car with my machine it would be magnet on the front passenger floorboard and detector in the trunk and thats the closest the 2 would ever come. But I would worry about speakers in my car at that point as well.

Welcome!
Good question. I have wondered myself if a magnet would mess with my MD or not.

they were selling super strong magnets to pull/filter out tiny iron deposits.

We're they selling these magnets for use in goldpanning? I don't really know if the magnets would bother a detector. We use the magnets out of old speakers, they're pretty strong. We attached them to the inside of our water scoops and stored the scoops in the trunk with the detectors. Didn't notice any difference in the performance of the detectors.

here is the warning that one of the sellers has next to their section where they sell the larget magnets............i think they do a good job of conveying what these things can do. These are neodymium magnets vice the standard ceramic magnets.

THESE ARE ABSOLUTELY NOT TOYS AND CAN BE VERY DANGEROUS! KEEP AWAY FROM CHILDREN!
THESE MAGNETS CAN EASILY CRUSH FINGERS!
WE WILL NOT BE HELD RESPONSIBLE FOR INJURY OR DAMAGE CAUSED BY THESE POWERFUL MAGNETS.
THESE MAGNETS ARE SOLD TO ADULTS ONLY AND REQUIRE
AN ADULT SIGNATURE UPON DELIVERY.


Beware - you must think ahead when moving these magnets.

If carrying one into another room, carefully plan the route you will be taking. Sensitive instruments like computers & monitors will be affected in an entire room. Loose metallic objects and other magnets may become airborne and fly considerable distances
- and at great speed - to attach themselves to this magnet.
If you get caught in between the two, you can be severely injured.
These magnets will crush bones in the blink of an eye.
Two of these magnets close together can create an almost unbelievable magnetic field that can be incredibly dangerous.
Of all the unique items we offer for sale, we consider these items the most dangerous of all. Our normal packing & shipping personnel refuse to package these magnets - our engineers have to do it. This is no joke or exaggeration - and we cannot stress it strongly enough. You must be extremely careful - and know what you're doing with these magnets.
Two Supermagnets can very easily get out of control, crush fingers and instantly break ribs or even your arm if opposing poles fly at each other.
A small child recently lost his hand when his father left two # 31 supermagnets unattended. The child picked one up and when he approached the other magnet on a nearby table,
it became airborne and obliterated his small hand.

Thanks for all the replies.
Dang! Those are some super duper strong magnets! I don't think the ones I was planning on getting are that strong. Those would definitely mess with a few things in my two seater truck esp. my credit cards!
As for Carol's question about goldpanning- my guess is that's what they're for.
If I remember what little physics I learned in high school correctly, a conductive metal passing through a magnetic field will produce eddy current (or whatever they're called- been almost thirty years since I left high school). An MD has wires and circuits which could generate the current if they were to come within a strong magnet's field, will the current be significant enough to damage microprocessors? Some MD's do have microprocessors, correct?

Wow... I had not realized how far magnets had evolved... I am sure these have applications. That being said, I cannot think of one reason I would need something like this... Well, maybe just to play with... RickO
