Magnetism: Electromagnetic Induction (Part 2)
from GCSE Science Simplified (All GCSE Science in one place) · host Thom Izod
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 signalsHow speakers and headphones do the reverse, converting electricity back into soundHow all of this is powered by the relative motion between magnets and conductors, and why energy is always conservedPerfect for AQA, Edexcel and OCR GCSE students who want to understand the real-life applications of electromagnetic induction and prepare for exam questions.
