Controlling fire color, ignition and a shape with magnetic field
<p>Few interesting experiments about the effect of magnetic field on fire ignition color and size when using a mixture of ferroelectric material (Iron oxide) and combustible material (Parafin Oil, paraffin). The effect of flame size and ignition can probably be explained by spikes increasing the material surface area, and the iron oxide act as a wick (like in a candle). The color switch when adding Boric Acid (B(OH)3 and sea salt (NaCl) when applying a magnetic field is harder to explain.</p> <p><strong>Procedures:</strong></p> <p><br> <strong>a) Flame color changes when applying a magnetic field (no idea why this happens)</strong><br> 1) To a small glass, add 16 ml of alcoholic gel (Dr. Fischer Alco-Gel 70%) or paraffin oil.<br> 2) Add one spoon of table salt (NaCl). Add one spoon of boric acid (B(OH)3). Add one spoon of Magnetite (Fe3O4) powder and stir.<br> 3) Pour a drop of the mixture on a glass plate and ignite. Use the magnet below the plate to control the flame color. <br> 4) To change the flame color from blue to red, put the magnet directly below the flame. <br> 5) To change the flame color from red to blue, move the magnet sideways along the plate.<br> To extinguish the fire, cover the flame with a small bowl.</p> <p><strong>b) Using a magnetic field to control fire ignition extinguishing and flame size.</strong><br> Ferromagnetic wax preparation:<br> 1. Add two spoons of paraffin wax (or oil) to glass (4-5 grams) and heat until the wax melt (60-100C).<br> 2. Add two spoons of magnetite (Fe₃O₄) powder (6-7 grams) to the melted wax. <br> 3. Mix until getting a uniform black solution and cool until the wax solidifies.<br> Usage: 1. Put a small amount of the ferromagnetic wax on a glass plate. 2. When touched by flame, the material will not ignite unless exposed to a magnetic field. 3. To enable ignition put a magnet directly below the wax. 4. To increase flame size, put the magnet directly below the fire. 5. To reduce the flame size or to extinguish/suppress flame put a magnet below the fire and move it sideways along the plate (fast movements will extinguish the fire).</p> <p><strong>c) Controlling flame movement with magnetic field:</strong></p> <p> First, create a flammable magnetic material (most standard ferrofluid will do well for this) <br> The ferrofluid can be prepared by the following steps<br> 1) Add about 6 ml of flammable oil (Parafin Oil or WD-40 oil works great). <br> 2) Add one spoon (about 8 grams) of Magnetite (Fe3O4) powder or any other ferromagnetic powder. <br> 3) stir until you get a uniform black mixture<br> Experiment:<br> 1) Pour a drop of the mixture on a glass plate and ignite. <br> 2) Use a magnet from below the plate to control the flame. <br> 3) To extinguish the fire, cover the flame with a small bowl. </p>
