SLOW MOTION SCIENCE!  Ferrofluid dropping on magnet

The observation which puzzled me was the formation of 'spoked wheel' like splash (2:34 - 2:40) occurring when the ferrofluid was dropped on the styrofoam surface situated directly above the magnet. I think it could be due to the relatively stronger magnetic fields influencing the ferrofluid splash thus changing its dynamics, as in this case the magnet was closest to the ferrofluid than in other cases. I am not an expert on magnets or magnetic field interactions rather an aerospace researcher, so I have no knowledge of why this phenomenon occurs. Will you be able to shed some light on it? Also, please repeat this particular experiment in slow motion to confirm the reproducibility of this observation and on other surfaces like glass, plastic, or non-ferromagnetic metals (if its feasible and interests you too). Please share your thoughts on it. Thanks Ravi.
