How to make an
electro-magnet
Things you will need:
Attach one end of the wire to one side of the
battery. Wrap the wire in a coil around the nail and attache the other end
of the wire to the other end of the battery. The nail will now be
magnetized. If you break the current, it will lose its magnetism.
An electro-magnet can be big or
small and runs on electricity. An electro- magnet is made of a piece of iron
or steel. The steel or iron is attached to a wire which is attached
to a battery. Electro- magnets are used in doorbells and school
bells. They are used in other things too. Electro-magnets and normal
magnets have molecules that are put together to make electrons. If
you take the electric current away from an electro-magnet it will not
work until you turn it back on.
