Magnetic Coins: 1992 UK 2p and a Magnetic Key Box 20 years on - Robin Linhope Willson
by Robin Linhope Willson, a former Professor of Biochemistry at Brunel University, UK. It is published by Ciencias y Artes Patagonia (www.capat.org) as part of the celebrations marking 20 years of educational projects by the Magic Penny Trust (www.magicpenny.org). The magnetic key box, or another very similar, was used in the pioneering experiment, at the Royal Institution, London in January 1993 when it was shown the then new UK 1p and 2p copper-plated steel coins, suspended from a magnet, could be rapidly spun by blowing. In this video the coins are standing on a flat surface and are not in contact with the plastic ruler on which the keybox, with ceramic block magnet attached, sits. This experiment could have also been done in 1992! But as far as we are aware no one thought of it, or thought it was impossible. The secret lies in very finely adjusting the distance between the coin and the magnet so that the effects of gravity just exceed the attractive force due to the magnet. Here, after 20 years experience, playing cards were used to do this. Further information can be found at http://www.MagneticCoins.info with links to many related photographs and videos. Patrick (Riley) and Charles (Tyler ) are Trustees of the Magic Penny Trust. Daniel (Harris) is a computer engineer who assisted in the development of the Magic Penny magnet kit and the associated book "Investigating Magnetism".
