Magnetic Coins - Circle Packing
Engineering Bridges with UK, Singapore and Uruguay real magnetic coins.
The above bridges, of real magnetic coins, were constructed in Patagonia, Argentina, by Robin Linhope Willson, formerly Professor of Biochemistry, Brunel University, UK.
They form part of the celebrations surrounding the issue of the newly magnetic UK 5p and 10p coins dated 2011 and twenty years of educational activity by the Magic Penny Trust.
The coin bridges connect Magic Penny ceramic block magnets (just visible) attached to food cans (out of shot).
The near perfect close packing of the 5p and 10 p coins in the manner shown, gives the structure remarkable strength, and enables spans of such lengths and weight to be constructed.
The Singapore dollar and Uruguay 1 peso coins are respectively the largest and smallest magnetic coins so far identified by Ciencias y Artes Patagonias and the Magic Penny Trust.
