An intriguing case of real-life physics: the tilting of Venezuelan coins in the Caracas Metro

We present an interesting and appealing phenomena, first observed by youngsters, which occurs when Venezuelan coins are placed on the floor of the passenger wagons of the Caracas Metro, the underground transportation system of the city. The phenomena - which consists of the upward tilting and occasional fast spinning of the coins, and even the formation of long chains of coins which can be made to hang from a hand - are excellent, highly motivating, examples of real-life physics and can be presented at different levels of education. To explain the behaviour of the coins, we construct a physical model, and then obtain the value of the magnetic dipole per atom in the coin, which is of the same order of magnitude as the Bohr magneton, the natural unit of the atomic magnetic dipole moment.
