Electromagnetic Induction • Basics Emf = voltage which maintains the electrical current of circuit Electrical power supplies could be for example batteries,accumulators But how it is possible to convert mechanical energy into electrical energy? Rotating steam turbine • Faraday’s and Lenz’s law Experiment in figures below • The bar magnet is moved towards to coil or away from it Electrical current is induced into coil • The direction of I depends on wether the flux density B is increasing or degreasing with time Generator N B N B emf Magnetically induced currents Principles developed 150 years ago • FARADAY’S LAW S Magnetic flux density B increases S Magnetic flux density B degreases 21.2.2014 Jarmo Lilja TAMK Fysiikan laitos 7
