Hi,
I am interested in electronics, and have been reading about electromagnetic inductance.
I have experimented with ac inductance for the last few weeks, but was wondering what can be done using DC power. I heard that DC can be supplied to a primary induction coil, then once switched off, a voltage spike would appear on a secondary coil. If this is true could a bulb be seen to flash if attached to the secondary coil. I did try experimenting with this but got no results, maybe I did not have the correct amount of windings?
