The difference between magnetic materials and magnets. * A magnet is an object that produces its own magnetic field. * A magnetic material is an object that can be influenced by a magnetic field and has the potential to become a magnet. 2. Examples of magnetic materials. * Including the elements Nickel, Cobalt, and Iron. * Also covers alloys of these elements, such as steel. 3. The distinction between permanent and induced magnets. * Permanent magnets produce their own magnetic field all the time. * Induced (or temporary) magnets only produce a magnetic field temporarily. 4. How induced magnetism occurs. * When a magnetic material is placed in the magnetic field of a permanent magnet. * The force between a permanent magnet and an induced magnet is always attractive. 5. Magnetically soft and hard materials. * Magnetically soft materials (e.g., iron) lose their magnetism quickly. * Magnetically hard materials (e.g., steel) lose their magnetism slowly. *** CHAPTERS *** 0:00 Introduction to Magnetic Materials, Permanent and Induced Magnets 0:21 The Difference Between Magnetic Materials and Magnets 1:00 What Materials are Magnetic? 1:23 Permanent vs Induced Magnets 1:43 How Induced Magnetism Works 2:27 Magnetically Soft and Hard Materials *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
