I am a student of the electrical engineering in the university of Munich. I tried to solve a homework but I have some difficulties.
I have tried to use different methods. unfortunately, unsuccessfully.
I will be very glad if you could help me. in fact I wanted to calculate the mutual inductance of two rectangular loops ( very thin wire) . both loops are identical and lie in the same plane. (Length c; wide b, a-b is the distance between them …see picture please) only in one of both loops flows strom I.
I have tried to calculate directly with the Neumann's formula, however, I get a very difficult integral, impossibly to solve:-( I have also tried to calculate the B field only in the center of the second rectangle (I’m not sure if that’s right). however, ordinarily the B field of (the first rectangle) must be calculated everywhere and then its flux in the second rectangle)
I have tried over again to accept the first rectangle as two very long thin wires and then to calculate the B field of both wires and then their flux in the secod rectangle, however, I do not know if the approach is right. as said I am a little bit lost :grumpy:and need your help.:cry: I will be glad if I will get a feedback from you .
I apologise for my bad english:blushing:http://www.imagup.info/images/03/1181839013_induc.jpg [Broken].[/URL]
I wish you a nice day!

try right subforum.

and write down more of what you have done to solve this, maybe you started out right and then did something wrong.

ti have tried o calculate the B field of both wires and then their flux in the second rectangle, however, I do not know if the approach is right...i am not sure that the uppon and the under wires have a flux in the second rectangle...i think that only the flux of the right and the left one must be calculated...please help me
