Just add it to the magnet dangers.

So; a precaution that should be mentioned by a physician to the heart patient has become a public panic.

Close contact - within about 3cm - with a neodymium magnet is enough to destabilise these life-saving heart devices...Ordinary iron or ferrite magnets, which are a dull grey colour with a low magnetic strength, are of little concern.

At least they mention that part.

I doubt very much that rare-earth magnets, like the neodymium-iron-boron ones mentioned in the article, are used for fridge magnets. I have used these things, and played around with them too. If you stuck one on your fridge, it would be very hard to get it off (I've done that on filing cabinets). But they have been used for many years in other applications, like speakers, so this is really nothing new.

I have heard for years that intense electro-magnetic fields can interfer with pacemakers.

Ask your doctor if refrigerator magnetics are right for you.

I have to agree with swift on this one. Neodymium magnets are STRONG, and using them as fridge magnets seems a little ridiculous, as it would be next to impossible to get them off the fridge. I have several, and as fun as they are to mess with, they would not be the magnet of choice for something that you want to be easily movable or removable.

Oh deer,

I better be careful with my 1"(122g) cube neodynium magnet when out and about...

I've heard that pacemakers are affected by magnetic/electrical feilds but I didn't know it was that dangerese..

Very strong magnets made from neodymium-iron-boron, which are shiny and silver in colour, have only recently become available.
No they're not, neodymium magnets are grey but very britle and they corrode easily so are often plated with nickle... Which is shiny silver...
