Chapter 13, sub-chapter 2: magnetic poles
Chapter 13, sub-chapter 2: Magnetic Poles Taken from the Cambridge Checkpoint Science Coursebook stage 8.✌ Welcome back to my blog★ In this blog post, I will be re-writing a sub-chapter from my Science coursebook. There will also be a video that is about magnetic poles. Magnets attract magnetic materials. There is a magnetic force which pulls on a piece of steel when a magnet attracts it. You may have noticed that the force is strongest if you use the end of the magnet. A bar magnet's magnetism is strongest at the ends. The ends of the magnet are called its magnetic poles. The poles are called the north pole (N) and the south pole (S). Why is this? If you hang up a bar magnet so that it is free to turn around, it will turn until one end points towards the north - this end is the north pole of the magnet. The south pole points towards the south. Two magnets The diagram shows what happens when the poles of two magnets are close together. They may attract each other, or they may repe
