Is it possible to shrink a quarter to the size of a dime with magnetism? I saw an offering on ebay for just such a coin and was wondering if it is a scam?

Other readers might at least have taken 10 seconds to do a Google search before dismissing this out of hand. It is indeed possible: see for example: http://205.243.100.155/photos/shrinker5.pdf
It's done by _inducing_ a magnetic field in the quarter by means of an electric current. In other words, it's effectively an electromagnet, which is something you can easily make with any metal, not just iron-bearing metals (any cub scout could tell you that).
In this case, the electric current is so huge that the resulting magnetic field makes the coin collapse.

You don't need magnets to shrink money; it does that all by itself. A quarter, today, is worth about as much as a dime was worth twenty years ago.

Um, sounds pretty scammy to me. Why turn a quarter into a dime anyway? It makes more sense to turn a nickle into a quarter, which CAN be done - just put it on a railroad track and let a train run over it.

You can't shrink a coin with magnetism !
It could be a trick instead of a scam, is it filed under /games/magic tricks or something similar???

With magnetism? Nope!

**My apologies**
It looks like its legit. The process is unbelievable, however... read over the link RickB has posted to see how it was done.
Really cool find. Thanks for the post. Kudos RickB!
