Solve a rotating-coil electromagnetism problem by deriving the induced emf from changing magnetic flux. Learn how coil area, number of turns, rotation rate, and magnetic field strength set the emf ...

Discovery and understanding of electromagnetic induction are based on a long series of experiments carried out by Henry and Faraday. If North-pole of a bar magnet is pushed towards the coil, the ...

CBSE Board Exams 2020 for Class 12 are going to start soon. Many students preparing for CBSE Class 12 Physics Board Exam often ask about important MCQs (Multiple Choice Questions) and in this article, ...

As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...

Discover how a rotating coil placed in a magnetic field generates an induced EMF. This video explains the core physics behind electromagnetic induction, showing how motion, magnetic flux, and ...
