When external current to an inductor is suddenly cut off, the inductor responds by temporarily producing a large EMF that can light a light bulb. In this way, a 6 V battery can momentarily illuminate ...

You also don’t get big voltage spikes caused by back EMF, which depending on your application could be a plus or a minus. But if you need an ungainly inductor in a circuit for its phase response ...

[Tuomas Nylund] wanted a way to visualize the electromagnetic fields (EMF) around him ... He admits that this isn’t much more than just an inductor connected to the probe and should not be ...
