Experiment: Faraday?s Law of Induction

Product Overview

Objective: Generating a voltage pulse in a conducting loop by the motion of a permanent magnet When a permanent bar magnet is allowed to fall in succession through a set of identical induction coils connected in series a voltage is induced in each of the coils. The voltage amplitude increases from coil to coil as the magnet moves through each coil as the velocity of the magnet increases steadily. However the magnetic flux that is calculated by integrating over the observed voltage curve has the same value for all the coils. Cyclic processes in thermodynamics can be plotted as a closed loop in a p V diagram. The area enclosed by the curve corresponds to the mechanical work taken from the system. Alternatively the mechanical power associated with a complete cycle can be determined and then the mechanical work can be calculated from that by means of an integration over time. This will be investigated in the course of an experiment using a Stirling engine.? Coach 7 license and computer required!
