Supposing it could be possible, what would happens if you wrap a secondary
coil (with the diode) around the actual relay coil?
All the magnetic collapsing field would be drained by this secondary coil
in short (by the diode), with few energy generated at the primary coil, is
this correct or not?  How this work in a regular transformer where the
secondary has a shorting reversed diode and you interrupt the primary
current?  The "current still flowing under field collapsing" is correct,
but only when you don't have any other way to drain the energy. The
secondary in short (by the diode) could minimize the induced energy at the
primary.
