- Hold one end of the copper wire
and come in around 2 inches from
- Start wrapping the wire tightly
around the nail (leaving around
½ inch at the starting end
of the nail) so that you create
a coil around the nail as many times
as you can (leaving around ½
inch at the end of the nail).
- Position the Rubber band to wrap
around the battery so that the negative
and positive ends of the battery
are covered by the rubber band.
If you choose to use blu tack this
step will be covered later.
- Position one end of the copper
wire under the rubber band at the
positive (+) end or the battery
or place blu tack on top of the
wire to hold it in position.
- Position the other end of the
copper wire under the rubber band
at the negative (-) end of the battery
or place the blu tack on top of
the wire to hold it in position.
- Hold the positive (+) end of
the battery (up position) and the
negative (-) end of the battery
(down position) between your thumb
and pointer finger to hold the wires
- Hold the coiled nail with your
other hand and try to pick up the
- If you disconnect one end of
the wire from the battery what happens?
Disconnect the battery at both ends
when you have finished allowing it
Try not to leave your battery connected
for long periods as it will drain
all the energy from it and the components
can get very hot and may burn you.
This electric current creates a
magnetic field that magnetizes the
nail. When the current flows through
the wire it produces a magnetic field.
A battery has negative (-) end and
a positive (+) end.
