The Japanese lady is making this happen varying the magnetic field by passing complex electric signals through it. it must take a lot of complicated maths to work this out, then sending the signals from a computer into a digital to analogue converter and then to the electromagnets, which also act as a feedback sensor as the ferrofluid going past them generates other electric signals..

She studied physics at normal graduate level, then fine arts at post graduate and another course (it looks like she has not just one but three University degrees) and is a Professor!

Even then it took about 7 years from her first concept to make those designs..

Nice bit of background info there .. cheers 🙂
