I posed an electro magnetism based question to an American Scientist this eve, hopefully sheddin some light on possible solutions for my Electronic dress!

"Hi there, possibly a strange request!

I'm currently designing a semi electronic dress for a computer game art course where I'm attempting to realise game based concepts in real life. My idea for this dress was that it would move using repelling magnets to move plates of wood in a fairly random form and would have slight perpetual motion based on the movements of the model wearing the dress. My question to you is wether I would need two electro magnets to repel the wooden panels or whether I would require a permanent magnet and the electro magnet (obvsiously the current would only flow to activate the magnet when the panels touched, I can send you diagrams if you wish).

Sorry this is probably a very long winded way of asking how to tell what polarity an electro magnet is, if they even have polarity, and how I would make one repel.

thanks"

and there you have it, the ramblings of a madman
