Magnetic poles

Science

The magnetic field of a bar magnet

Electromagnets

Current through an electromagnet

Using electromagets

In the Electromagnetism unit, they will build on this knowledge to learn about the motor effect and electric motors, the generator effect and electric generators, and how loudspeakers and microphones work.

In the Series circuits unit, pupils learnt about static electricity (electric charge), setting up series circuits using circuit diagrams, finding and replacing faulty components, and the rules for electric current and voltage in series circuits.

This unit explores magnetism, including magnetic poles, fields, and Earth’s magnetism, along with the principles of electromagnets and DC motors. It focuses on conducting precise scientific enquiries and identifying variables and emphasises accuracy, repeatability, and reproducibility.
