GCSE Physics - Permanent & Induced Magnets #77

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.

What is the difference between a magnetic material and an actual magnet?

What are some examples of magnetic materials mentioned in the text?

Can you explain what induced magnets are and how they are created?

How does the force between a permanent magnet and an induced magnet behave?

What distinguishes magnetically soft materials from magnetically hard materials?
