Would someone please try this?
 
I would, but I don't have an electromagnetic conductor.

How to Shrink a Quarter Using Electricity

Electrically conductive metals, such as copper and aluminum, can be altered in form without bringing so much as a chisel to their surface. The secret: electromagnetic fields.

By inducing a high-intensity pulsed magnetic field into—in this case—a quarter, a corresponding repulsive magnetic field is created, rapidly—we're talking 1/100th of a second, here—repelling portions of the quarter into itself. What results is a fat, dime-size 25-cent piece.

What You Need
• A coin
• An electromagnetic conductor
• A heavily constructed coil of wire


Step by Step
• Place coin in close proximity to wire coil.
• Discharge electromagnetic current through conductor, by closing its circuit.
• The current creates a ultrastrong, rapidly oscillating electromagnetic field around the wire coil.
• In turn, the coil creates an ultrastrong magnetic current (tens or hundreds of thousands of amperes), which overcome the coin, causing it to alter in shape and size.

Sounds like a good Mythbusters test.

Yep. It worked.

Someone should make one of those box things at zoos and science museums to put next to the one that flattens and stamps your pennies.

So..... for just 51 cents you could have a tiny penny to go along with your koala-stamped penny. Or a tiny koala stamped penny.

Wouldn't a source of electricity also be required?

probably take twice as many of those little quarters to buy a rubber.

I don't even know what an electromagnetic conductor is...a big fancy magnet?

It's kind of self explanatory.

I call bullshit on this one. No way.

Dave Lane 04-18-2012 10:04 AM

OK it is possible. Heres all you need :)


In order to shrink coins, we charge up a high voltage capacitor bank that consists of two to four large "energy discharge" capacitors. These are specially constructed low-inductance, steel-cased capacitors that can each deliver up to 100,000 amperes (100 kA) at up to 12,000 volts. Each capacitor measures 30" x 14" x 8", weighs 165 pounds, and is designed to have an expected lifetime of over 300,000 shots at 100 kA/shot. A double pole double throw (DPDT) high voltage relay is used to connect the capacitor bank to either a high voltage DC charging supply, or to a group of high power "bleeder" resistors. A 15,000 volt transformer and a set of 40 kV rectifiers make up the DC power supply that charges up the capacitor bank.

Do they have a practical use outside of a lab?

I dont have an electromagnetic converter, but I do have a flux capacitor. I tried putting the quarter in the flex capacitor. It turned into a penny.

Jesus. I think Rain Man is trying to eliminate his enemies...

I gave this gal a rectifier in college. She slapped me silly.

Did she tesla to stop?
