The video tutorial explains the concept of magnetic materials and distinguishes between permanent and induced magnets. It clarifies that not all magnetic materials are magnets and highlights key magnetic elements like nickel, cobalt, and iron, along with their alloys. The tutorial further explores the characteristics of permanent magnets, which have a constant magnetic field, and induced magnets, which temporarily gain magnetism when exposed to a magnetic field. It also discusses how some materials lose magnetism quickly, termed as magnetically soft, while others, like steel, retain it longer, known as magnetically hard.
