Physics Unit 7 - Electromagnetism
Electromagnetic effects are used in a wide variety of devices. Engineers make use of the fact that a magnet moving in a coil can produce electric current and also that when current flows around a magnet it can produce movement. It means that systems that involve control or communications can take full advantage of this.
In this final physics unit students will look at the difference between permanent and induced magnetism. They will investigate how we can vary the strength and direction of a magnetic field. Students will learn about Flemings left hand rule and how the direction of a magnetic field around a wire and solenoid can be determined. They will use their understanding of the link between electricity and magnetism to describe how a motor works.
