I take a 12 volt battery, take a strong electromagnet, and fire it up.
I then touch the two terminals that are currently connected, one terminal of the battery, and one terminal of the electromagnet.
When I disconnect the terminal of the electromagnet to one terminal of the battery, while still placing my thumb over the terminal of the electromagnet and the battery, I receive a little shock.
I know that the inductor releases a higher voltage when disconnected, but why?
•The magnetic field is induced with an inductor with X amount of turns when the battery is connected.
• The battery is now released, and the magnetic field closes down, and induces a current on the inductor with X amount of turns.
Heres where I am confused- both X's are the same amount of turns, therefore a 1 to 1 ratio. Why are different voltages present with the same voltage source, a 12 volt battery?
