How can magnetism be created
Web8 de set. de 2024 · Magnetism can be described as a force that attracts and repels magnetic objects. This force is mediated by magnetic fields that penetrate different media. Some materials naturally have magnetism as a default property. However, certain materials can be magnetised or demagnetised according to the requirements.
