    A flywheel diode is often required, because when the current through an inductive load is suddenly broken, a back EMF will build up as the magnetic field breaks down, and if there is no path for the current, a high voltage builds up. The high voltage can damage a transistor or cause arcing in a switch. The flywheel diode is connected in reverse across the load, and provides a path for the current so the magnetic field and current can safely decline.

    there is a copy of the circuit i am working with, sorry i dont know how to post images


    when the flywheel diode is attached it will be connected in parallel across the inductor and resistor
