This video shows the behaviour of a candle flame in a high DC magnetic field. First the DC magnetic field produced by a Helmholtz coil with hard-steel poles (built by me) is characterized, then the qualitative behaviour of a candle flame in this high magnetic field is shown.
*I must make a small clarification. In the video it is said that ferromagnetic materials are magnetically very 'susceptible' because even a small value of H-field leads to a big value of B-field. Rigorously, a magnetically very 'susceptible' material is one for which even a small value of H-field leads to a high value of M-field (not B-field). Since the B-filed (neglecting a multiplicative constant) is the sum of the H-field and the M-field, and since in a ferromagnetic material the M-field dominates over the H-field, one can 'confuse' the M-field with the B-field.

Thanks to [ Ссылка ] for making me the hard-steel poles!
