Magnetic poles and non-contact forces

Magnetic poles and non-contact forces

Bar magnet with field lines leaving the north pole and entering the south pole outside the magnet

A magnet produces a magnetic field around itself. Another magnet placed in this field experiences a push or pull, even when the magnets are not touching, so magnetic force is a non-contact force.

  3. /12.1 Magnets and magnetic fields

Step-by-step lessons on Edexcel GCSE Physics 12.1 Magnets and magnetic fields, covering 12.1.1 Magnetic poles, 12.1.2 Magnetic materials; permanent and induced magnets, 12.1.3 Magnetic fields, and 12.1.4 Plotting compasses and the Earth's magnetic field. 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.
