Comsol and I'm trying to model a 3-coil transformer

Hi all, I am new in Comsol and I'm trying to model a 3-coil transformer consisting of primary coil, Secondary coil, tertiary coil . Basically, there will be a voltage source supplied to the primary coil . Secondary coil and tertiary coil which is placed beside it. will pick up the magnetic field produced by the primary coil and thus current will be induced in the secondary coil. but tertiary coil are not magnetic exited with primary coil .
What I have done so far is, I use AC/DC module where I set multi-turn domain to all the coils and I excite the coil with circuit. There is a AC voltage source connected to the primary coil . But I do not see any change voltage /current (zero) in tertiary coil.
plz help me....
