Revise Edexcel GCSE Physics 12.2.1 Magnetic field around a current-carrying conductor with the revision guides.
Describe how to show that a current can create a magnetic effect around a long straight conductor, describing the shape of the magnetic field produced and relating the direction of the magnetic field to the direction of the current. • Recall that the strength of the field depends on the size of the current and the distance from the long straight conductor.
