Hi. I was wondering how strong an electromagnet would have to be to move water, such as a low stream from a tap or something.. I searched the forum a bit to the answer to this, and while i did discover that an electromagnetic field of sufficient strength will move water, the strength required was not described. The reason i ask is because i was thinking of making a modification to one of those tabletop water feature fountains as a gift idea. Is this even possible? Is there a better way? Or should i just go with a voucher or something... Thanks in advance.
