Isolation of Gravity Effects on Diffusion Flames by Magnetic Field

We present the experimental demonstration of the ability of magnetic field to remove buoyancy effects on flames. The experiment consists to observing the shape and colour changes of a laminar jet diffusion flame located in the air-gap of a Bitter magnet able to delivering up 650 T 2 /m in magnetic gradient intensity. At some critical (predicted theoretically) value of the upward magnetic field gradient strength, the flame becomes nearly hemispheric and free of soot similarly to flames at zero-gravity in drop towers.
