Electromagnetic Induction

The video tutorial explores the relationship between moving electric charges and magnetic fields, explaining how moving magnetic poles create electric fields. It introduces the concept of induced electromotive force (EMF) and Faraday's Law of electromagnetic induction, which describes the relationship between changing magnetic flux and induced EMF. The tutorial differentiates between EMF and electric potential difference, highlighting the non-conservative nature of fields induced by changing magnetic flux. It also expands on Faraday's Law by introducing the concept of multiple loops and the factors affecting magnetic flux, concluding with a definition of electromagnetic induction.
