What is magnet? - Magnets and Forces - Year 3

A magnet is an object that is capable of exerting a magnetic force, which is a type of physical force that can attract or repel other magnets. This magnetic force is most powerful at the magnet's ends, known as the north and south poles. When two magnets are brought close together, their poles interact with each other. If the same poles of two magnets (either two north poles or two south poles) are facing each other, the magnets will push away from one another, which is known as repulsion. Conversely, if opposite poles are pointed towards each other, with one north pole facing a south pole, the magnets will pull towards each other, an effect called attraction. These magnetic forces are invisible but can be felt as the magnets move in response to one another.

When exploring the concept of a force, it is important to understand that it refers to an influence that can cause an object to change its movement, direction, or shape. In the case of magnetic forces, they are not seen but are detected by the movement of magnets either coming together or moving apart. The interactions between the poles of the magnets demonstrate these forces clearly, showing either a pushing or pulling action depending on the orientation of the poles. This fundamental property of magnets and their forces is a key concept in understanding how magnets work and interact with each other and their environment.
