| Abstract | ||
| The effect of magnetic field on the candle is the basis of explanation the effect of magnetic field on flames. The magnetic field enhances combustion process between fuels, which are diamagnetic material and oxygen which is paramagnetic material. It is found that a free convection heat transfer from candle flame may be significantly affected by the presence of a magnetic field; this effect appeared in the increasing of flame height and luminosity and brightness of candle flame. When pyrex tube fixed around the candle with lack of oxygen, candle flame quenched after10 seconds. In the presence of magnetic field, candle flame life increased to 22 seconds. When these experiments repeated to allow oxygen to entry from bottom of the candle, the flame quenched after 25 seconds without magnetic field and reached to 40 seconds with it. This means that the magnetic field increases oxygen concentration. Because of the oxygen is paramagnetic material, the magnetic field increases the oxygen concentration around the candle flame and the magnetic field enhances the buoyancy force of the candle flame. This means that there is a complete combustion in the presence of the magnetic field. | ||
