Magnets are substances that display magnetism due to the movement of the electrons within the atoms of the substance. The movement of the electrons causes moving electric charges. Iron is the most common magnetic substance.
Each magnet has two poles. These poles are often described as the “north” and “south” poles of a magnet. The forces between the poles of two different magnets can be either attractive or repulsive.
- Two south poles of two separate magnets will display a repulsive force.
- Likewise, two north poles of two separate magnets will display a repulsive force.
- An attractive force exists between the north pole of one magnet and the south pole of another magnet.
The magnetic field is the area around the magnets within the magnetic force exists. A magnetic field can exist between opposite poles of two separate magnets. A magnetic field can also stem from the south pole of one magnet to the north pole of the same magnet. Diagrams of magnetic fields can be viewed via the links provided below.
