Will an ordinary toy magnet ever wear out?

Answer 1

Yes overtime most common magnets do ware out (only if mishandled). Only a select few (permanent magnets) won't. One of the most common permanent magnets used in most speakers are comprised of NeFeBo. Permanent magnets are very strong and do last forever as their particles never unalling.

If you don't hover another magnet over it or rub it than you should be fine.

Answer 2

Uh, it depends. If the magnet is made out of something like magnetite than no, at least certainly not anything that you could ever be around to whitness. However, if it is just a piece of metal like steel that has been magnetically aligned with magnets then yes, it certainly could. And probably would. Sometimes, especially on cheap toys, instead of using magnetite which is more expensive, they will magnetize stell by running the magnet down the side of the steel. One easy way to show how this works is with a nail and a magnet, all you have to do is rub the magnet down the side of the nail and you can pick up things like paperclips for a while. This magnetism however is much weaker. If you were to hit the nail with a hammer or use it as a magnet too much, the magnetic particles inside would disalign and it would just be an ordinary nail again.

Answer 3

It should last at least your lifetime as long as it has a keeper. That is a metal strip between the poles, or another magnet, or just stuck to the refrigerator door.

Answer 4

yeah when the iron and nickel atoms in the magnet decay to nothing, which is about 50000000 trillions of years maybe?

Answer 5

Only if you treat it roughly, like getting it very hot or subjecting it to shock such as a hammer blow.

Answer 6

no

Answer 7

no
