Mutual inductance

  1. May 12, 2005 #1
    I have 2 inductors in series...iron core...iron yoke...with a capacitor in parallel. For best mutual inductance, does it matter which direction each coil is wrapped...or maybe a better question would be how do you insure that the poles will be opposite every cycle so they are not working against each other?

    If they are in series, then you effectively have a single coil. Mutual inductance becomes self inductance (which is just inductive reactance). The induced voltage/current will always oppose the applied voltage/current (Lenz's law) regardless of how you orient the coils. Just thinking about it quickly, the inductive reactance should be the same regardless of the orientation - it depends only upon the inductance.
