Hair dryer X-ray. The electrically heated filament (coil, centre) has air passed over it (from left to right) by a fan (centre left). This causes hot air to be blown out through the nozzle (centre right), which is used to dry wet hair. Switches (lower left) can be used to change the speed of the fan.
