ECE 201 Circuit Theory I 4
Apply the Right-Hand Rule
• Determine the direction of magnetic field established by the current

ECE 201 Circuit Theory I 5
Pick one terminal of the second coil
• Assign a current into this terminal

ECE 201 Circuit Theory I 7
Compare the directions of the fluxes
• If the fluxes have the same direction, place a dot at the terminal where the test current enters.
• If the fluxes have different directions, place a dot on the terminal where the test current leaves.
