i have started to use dot convention for magnetically circuit. my understanding is that if the currents for primary winding and current in the secondary winding are clockwise and the dots are ontop of the inductors then the mutual inductance value would be negative because the secondary winding current would be coming out of the dot rather then going in.
when both currents are going clockwise and the dot in the primary winding is on the top and the dot for the secondary winding is on the bottom then the mutual inductance values for the two current would be positive since both currents are going into the dot. but sometimes i see other places use different ways. can you guys help me understand the convention or provide me with what you do to understand the circuit?
thanks
