Re: [DML] Marc Goldstone/Automatic transmission computer



I think a simpler explanation of "emf" is to use the analogy of 
momentum and inertia. When you suddenly stop (turn off) the electric 
(DC) going to a coil (solenoid) the electric is still going (inertia). 
When it finally stops it "piles up" and arcs across whatever has a low 
breakdown voltage like a capacitor with a low rating. This is a very 
simplistic but easy to understand description of events. The idea of 
the "fix" is to allow the electric to "bleed off" harmlessly without 
damaging anything. In reality the problem is not exactly reverse emf 
but the sudden shutdown of the circuit without an allowance for the 
release of the "left over" electric which as Walt said was the 
magnetic field. Reverse emf is a term applied to the effect observed 
more commonly in motors.
