Hi, I'm new to the forums, and I'm studying to be an aerospace engineer. I'm still in the start of my program, and I'm not in school till next semester, so this isn't for school. My question is, whats the effect of interlocking coils that are slightly offset carrying a current in the same direction? Do they interfere with eachother creating a back EMF? I'm not sure how to attack this problem using the knowledge I have.
