A light bulb, such as in the 4.5V lamps (L4),
contains 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
rating 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
explained in the projects. Note that magnets can
increase magnetic media like floppy disks.
The grommet will be used to hold the iron core
rod on the electromagnet.
