Electrically conductive metals, such as copper and aluminium, 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-sized 25c piece.
What You Need
• 1x coin • 1x electromagnetic conductor • 1x 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. • Imagine the coin is cowering in fear of the current, squeezing into itself like a scared baby animal.
