What are the Forces between Magnetic Poles?
The forces between
North
and South magnetic poles
are similar to the forces between electrostatic charges.
Unlike poles
attract (pull
towards each other),
Like poles repel
(push away from each
other).
This means that two North poles will repel each other
and two South poles will repel each other.
One North pole and one South pole will
attract each other.
The further apart the poles are,
the weaker are the
forces between them.
You need to know the shape of the magnetic
field for
a bar magnet, poles which attract and poles
which repel.
Notice that the lines of magnetic
force
between the poles are parallel.
