Hi Tetiana / TanyaVery good article How critical are the size of the magnets, 5x5x30 seem difficult to find?You show a pattern in the 9 magnets and look like they are placed in a certain way, can you tell me how they are lined up.
Hi TanyaThank you for the offer of the magents but should be able to find similar ones on ebay...I have now learnt that rare earth magnets differ from ordinary ferrous bar magnets and can have poles along their length not just at the ends.Best Regards Richard
