The magnetic effect of a current

The magnetic effect of a current

A current-carrying conductor produces a magnetic field in the space around it. The field is produced by moving charges, so a wire with no current has no magnetic field caused by the current.

  3. /12.2 Electromagnetism

Step-by-step lessons on Edexcel GCSE Physics 12.2 Electromagnetism, covering 12.2.1 Magnetic field around a current-carrying conductor and 12.2.2 Solenoids and electromagnets. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
