A proposito di questo titolo

How do alternators, dynamos, microphones, and speakers all use the same physics? In this episode of GCSE Science Simplified, we continue exploring electromagnetic induction.

You’ll learn:

  • How alternators generate alternating current (a.c.) and dynamos generate direct current (d.c.)

  • How microphones turn sound waves into electrical signals

  • How speakers and headphones do the reverse, converting electricity back into sound

  • How all of this is powered by the relative motion between magnets and conductors, and why energy is always conserved

Perfect for AQA, Edexcel and OCR GCSE students who want to understand the real-life applications of electromagnetic induction and prepare for exam questions.
