Abstract
A device that emits colored flames is disclosed. The device may include one or more electromagnetic coils within a housing. A fuel source may provide fuel such as hydrogen to an igniter at the input to the electromagnetic coil. The fuel may be ignited and a current may flow through the coil that may create a magnetic field. The ignited fuel may ionize creating an electric current that may accelerate the combusting particles through the coil. The current may create a magnetic field that may force the ionized particles into cyclotron orbits. Coloring additive such as salts may be added to the combusting fuel to provide color to the resulting flames.
