The Big Idea – Objects can affect other objects at a distance.
In this topic we look at how magnets work be trying to visually the invisible magnetic field all magnets produce. It is this magnetic field that causes attraction and repulsion between magnets.
You must know that the same poles on a magnet repel each other and opposite poles attract each other. To understand why you must be able to draw magnetic field lines and describe how you visualised (saw) them in the classroom.
Can magnets be turned on and off? For a deeper understanding of magnets look at the year 8 page on Electromagnets to see how magnets can be really useful.
