This episode is an introduction to electromagnetic induction. The presentation is supported by many experimental demonstrations. The video covers the following topics: 1. Oersted’s discovery of the magnetic effect of an electric current (sometimes called the “motor effect” as it is the principle behind simple DC motors); 2. Faraday’s discovery of electromagnetic induction; 3. Magnetic flux; 4. Flux linkage; 5. Faraday’s law of electromagnetic induction; 6. Lenz’s law (or Lenz’s rule); 7. Eddy currents and their braking effect. Less
