Course Description

Magnetic fields is a topic within Edexcel A level physics.

In Edexcel A level physics, the study of magnetic fields is part of Topic 7: "Electric and Magnetic Fields".

Magnetic fields has some tricky concepts and is often considered the most difficult part of A level physics.  If you are clear about those concepts, then you can enjoy doing well in magnetic fields questions.
