Magnetise - GCSE Physics Definition

To magnetise something means to make it magnetic, which means it can attract certain types of metal like iron, nickel, or cobalt. This happens when the particles inside the material line up in the same direction, creating a magnetic field. You can magnetise an object by rubbing it with a magnet or by using electricity, such as passing an electric current through a coil of wire wrapped around the object. Once magnetised, the object can pick up small pieces of metal or stick to other magnets. In GCSE Physics, understanding magnetisation helps explain how magnets work and how they are used in everyday items like compasses and electric motors.
