Magnetic Domain

Key Stage 4

Magnetic domains are regions in the magnet with a particular direction of magnetisation, each of which act as smaller magnets.

For an object to act like a magnet the magnetic domains must be lined up in the same direction.


When magnetic domains are aligned the object has an external magnetic field so it acts like a magnet.	When the magnetic domains are not aligned there is no external magnetic field because the effect of the magnetic domains cancels out.
