Do you know what else scientists
have learned? Every magnet
has a
magnetic field
around it.
Inside that space, the magnet
canattractmetals like iron, nickel,
and steel. The magnetic force is
strongest close to the magnet.
And it is weakest at the edges of
the magnetic field.
Ever played with magnets like the ones on the next page?
Guess what you would figure out? The magnetic field of one
magnet can pull on (attract) or push against (repel) the
magnetic field of another magnet. That’s why the
north
pole
of Magnet A sticks to the
south pole
of Magnet B.
But it pushes away from the north pole of Magnet B.
Why do magnets act this way? They are trying to line up
withboth theirmagnetic fieldspointing in the samedirection.
