Hello I am trying to learn the deeper theory behind automotive and motorcycle electronics. I've read that current is induced when a conductor is moved through a coil OR the coil is moved around the conductor. I get the jest that movement is key.
More specifically I'm trying to see exactly what's happening when the spark jumps the spark plug. I'ver read that for this to occur the positive side connection to the primary coil is cut, thereby creating a voltage spike in the secondary coil resulting in the spark jumping the gap.
My confusion is I don't readily see what this disconnection does to cause the voltage spike. I understand that the secondary windings are 10 times the amount of primary windings and would have 10 times more volts (or around 120 volts with a 12 volt battery).
But why does collapsing the field in the primary cause the secondary to soar even higher creating enough voltage to jump the plug gap. Is this disconnection another facet of the "movement" semantics ?
Appreciate any info on this.
