Electric Motors and Transformers | IGCSE/GCSE Physics

Hello everyone- this video deals with electric motors and transformers.

The video starts by explaining magnets and magnetic fields.

The right-hand grip rule is covered to help find the direction of the magnetic field when a current flows.

Fleming’s Left Hand Rule is covered. The motor effect is explained right after.

The part of a simple motor like a permanent magnet, armature or rotor, commutator, brushes, axle and power supply is covered.

The 4 improvements to an electric motor are covered.

Transformers are covered including their parts.

Step-up Transformer and Step-down Transformer explained

and 2 equations relating to power and the ratio between voltage and n.o. coils covered too.

This video is good for IGCSE/GCSE students and KS3
This video is a great place to start for beginners
