Induced EMF and flux rule

  1. Dec 2, 2014 #1
    to calculate emf i can use the flux rule -d(magnetic flux)/dt or the lorentz force line integral across the circuit. Is there a gudeline to follow for knowing when to use either (or both) of these methods?

    Thanks :D

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    This depends on the geometry in the problem and data you know. For instance, in cases where you know area of a closed loop and can easy calculate coresponding flux it is better to use dΨ/dt.

    But is there a guideline?

    I don't know of any official read regarding this matter.
