Many thanks for your reply. I have been given the number if turns and the current that is flowing. In an earlier question I am given the permeabilities so can work out flux. Now with the correct formula I can would out inductance.

Homework Statement I have a magnetic circuit with a coil wrapped around the centre "leg" of the core as follows. I have been given average lengths, areas and permeabilities for the three legs and the airgap. Homework Equations L = (N^2*µ*A)/l The Attempt at a Solution For the...

Thank you very much. Those two documents were perfect explanations for this particular circuit, but I'll read them further so I gain a better grasp of the general principles as well.

Homework Statement I am looking for a general explanation of when the total reluctance of a magnetic circuit is not equivalent to the sum of the reluctances if each area. In several examples the text has added 2 areas in parallel and then added the third area. I'm not 100% sure on when this is...
