    Why is the mutual inductance term negative in the loop equations?

    I am reviewing questions from old studies. I believe it was to find Zeq at the terminals of the left hand inductor, by using a 1V test. But i think I answered my own question. For I1 running from - to + potential the loop equation needs to read 1+-j6*(I1-I2)=0 so that second loop equation...

    Why is the mutual inductance term negative in the loop equations?

    http://img638.imageshack.us/img638/989/newbitmapimagety.png I am running my loop current equations for this circuit and have. -1+-j6*(I1-I2)=0 -j6*(I2-I1)+j20*I2 +j12*I3=0 (j30-j2+j5+4)*I3+j12*I2=0 But i am being told that the mutual inductance term j12 should be negative in both. My...
