GALILEO’S PENDULUM AS A MAGNETIC BALANCE FOR STUDYING CHEMICAL MAGNETISM AT HOME

A very simple, but rich experiment, encompassing a classical Galileo’s pendulum, has been devised to be performed at home, especially during the Covid-19 pandemics. The experiment uses a miniature supermagnet rod as the pendulum oscillating element suspended from a fixed sewing thread. Its physics can be fully investigated, allowing to study the oscillation movements and to extract the gravity acceleration constant. The interaction with chemical substances can be accurately monitored by equilibrating the magnetic attraction of the probe as it opposes the gravity restoring force. Magnetic sus...
