Pulses of electric current as used in faradic treatment in physiotherapy departments are usually generated by electronic apparatus with facilities for pulsating the bursts of electric pulses. In older machines a faraday coil is used which generates the pulses by the interruption of current to an inductor (similar to a car ignition coil). The Smart Bristow faradic coil used in physiotherapy apparatus has a retractable iron core which is moved in and out of the coil to change the strength of the pulses.
