Electromagnets and Electromagnetic Induction _ GCSE Physics

The video tutorial explains the formation of magnetic fields around wires and how coiling a wire can create an electromagnet. It highlights the practical uses of electromagnets, such as in scrap yards. The concept of electromagnetic induction is introduced, explaining how a changing magnetic field can produce a potential difference, leading to alternating current. The video also describes how generators work by using a spinning magnet within a coil of wire to produce electricity for homes.

Explain the process of electromagnetic induction.

How do generators produce alternating current?
