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 ...

[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 ...

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 ...
