Magnets and Magnetic Fields: Field Lines, Compasses and the Earth | GCSE Physics

Magnets and magnetic fields for GCSE Physics, animated: poles, why like poles repel and unlike poles attract, and magnetism as a non-contact force. Permanent and induced magnets (why an induced magnet is always attracted), the magnetic materials iron, steel, cobalt and nickel, and for Edexcel the uses of steel and soft iron. Then field lines from north to south, why closer lines mean a stronger field, a uniform field, how to plot a field with a plotting compass step by step, and the Earth's magnetic field: why a compass points north, the magnetic south pole near the geographic North Pole, and the dipping compass. Two exam-style questions worked through (which way do the compasses point, and how to tell a magnet from plain iron) and five common mistakes.
