D4 practical: Falling magnet
In this practical a magnet will be dropped through a coil of wire. As the magnet passes through the coil an EMF is induced that is measured using the data logger. The acceleration due to gravity will be calculated by measuring the time taken for the magnet to pass through the coil. Set up the apparatus as shown in the diagram. Connect the coil to the data logger and make some test runs to adjust the sampling rate and...
