How electricity creates the invisible force of magnetism
In short: This video breaks down the fundamental principles of electromagnetism for the 2027/28 GCSE exams. It explains how moving charges generate magnetic fields and how to manipulate those fields to create powerful, controllable magnets.
The lesson covers the progression of magnetic fields from simple straight wires to complex solenoids. It demonstrates how the shape of a conductor—whether a straight wire, a flat circular coil, or a solenoid—dictates the geometry of the resulting magnetic field.
A key focus is the practical application of solenoids as electromagnets. Students learn to determine field direction based on current flow and identify four specific methods to increase magnetic strength, including the strategic use of an iron core. The content is tailored to specific exam boards like AQA, Edexcel, and OCR.
