Document Summary

Neb = nba due to current i flowing through solenoid. Tore only depends on geometry of device ! ( like capacitance ) L=nmqiha = ne mon a = mon " la. Self inductance: an inductor whose curren i changes over time (dat # o ) , experiences change in eb , across its ends . so a ( self - induced ) emf.
