An induced magnet is a material that becomes a magnet when it is placed in a magnetic field, temporarily acquiring magnetic properties such as attracting other materials like iron or steel. However, unlike permanent magnets, induced magnets can't repel other magnetic objects. They also only exhibit magnetism when they are within the influence of an external magnetic field, and lose their magnetic properties once the external field is removed. This is due to the alignment of the magnetic domains within the material, which align in the direction of the applied magnetic field. Induced magnetism is a key concept in GCSE Physics, helping students understand how various devices, such as electric motors and transformers, operate through the use of temporary magnetisation.
