Magnets


Magnets
Magnets are pieces of metal that attract iron

Different types of magnet

Bar magnet
Horseshoe magnet

Button magnet

Every magnet has two poles
N= North seeking pole
S= South seeking pole


The poles of a magnet is where the magnetic force is the strongest.
Iron filings sticking to thepoles of a horseshoe magnet

A magnet has lines of magnetic force around it
When we sprinkle iron filings on to a piece of paper laid over the magnet we can see the magnetic field lines


Rules about magnetic poles

Poles that are different (unlike poles) attract each other

Poles that are the same (like poles) repel (push) apart
