Voltage spike
If de-energizing an inductor causes a voltage spike, why doesn’t de-energizing a purely resistive circuit cause a voltage spike as well? If the reason for the voltage spike with an inductor is the magnetic field that it creates, then a purely resistive circuit should have a voltage spike given that a purely resistive circuit creates a magnetic field as well.
