Parts
A light bulb, such as in the 4.5V lamps (L4), con-
tains a special thin high-resistance wire. When a
lot of electricity flows through, this wire gets so
hot it glows bright. Voltages above the bulb’s rat-
ing can burn out the wire.
The electrical symbol for a lamp is shown here,
though other symbols are also used in the industry.

The electromagnet (M3) is a large coil of wire,
which acts like a magnet when electricity flows
through it. Placing an iron bar inside increases
the magnetic effects. The electromagnet can
store electrical energy in a magnetic field.
The properties of the electromagnet will be ex-
plained in the projects. Note that magnets can
erase magnetic media like computer disks.
The grommet will be used to hold the iron core
rod on the electromagnet.

OTHER PARTS
The magnet is an ordinary magnet
like those in your home.
The compass is
a standard compass.
The red needle will
point toward the
strongest magnetic
field around it, usually
the north pole of the
earth.
The iron filings are tiny
fragments of iron in a
sealed case. They
will be used in
m a g n e t i s m
projects.
The copper and zinc elec-
trodes are just metals that
will be used for electro-chem-
ical projects. They have
snaps attached for easy con-
nection.
The nut-snap is an iron nut
mounted on a snap for special
projects.
The string will be used
in special projects. You
can use your own
string if you need more.
The thin rod is an iron
bar for special projects.
The Paper Clips will be
used for special proj-
ects. You can use your
own if you need more,
but they must be metal.
The spare motor top is provided in
case you break the one on the
motor. Use a screwdriver to pry
the broken one off the motor,
then push the spare one on.
