In this tutorial will explain how to create a fire that change its color, from green to red and vice versa, when exposed to magnetic field. This is a part of general project of mine to find ways to control fire using magnetic fields.
It is well known that adding table salt (NaCl) to a fire change the flame color to red while adding boric acid to the fire change the flame color to green.
To create a flame that change its color in response to magnetic field I mixed boric acid and table salt (NaCl) with magnetite and with ethanolic gel. The magnetite is ferromagnetic which mean it respond to magnetic field. The ethanolic gel is combustible and responsible for the fire. The result is a fire that change its color when magnetic field applied as can be seen in the video above.
A ) Creating the flammable magnetic material
1) To a small glass add about 16 ml of alcoholic gel (Dr. Fischer Alco-Gel 70%). Ethanol can be used instead but it less effective and more dangerous.
2) Add one spoon of table salt (NaCl).
3) Add one spoon of Boric acid.
4) Add one spoon of Magnetite (Fe3O4) powder.
5) Stir until you get uniform black mixture.
B) Controlling the color of the flame using magnetic field
1) Pour a drop of the mixture on a glass plate and ignite.
2) Use magnet below the plate to control the flame color.
2.1) To change the flame color from blue to red, put the magnet directly below the flame.
2.2) To change the flame color from red to blue, put the magnet below the flame move the magnet sideways along the plate.
3) To extinguish the fire cover the flame with a small bowl.
