The Blacksmiths' Induction Forge
An induction forge uses the principle of electro-magnetic induction to heat metals and is remarkably quick, very green and efficient.
The metal being heated is placed inside the water cooled coils and many thousands of Amps are passed through them. This induces a short circuit current in the metal and causes it to heat up ...rapidly. The temperature can get to close to 1500 C in seconds.
