1. The problem statement, all variables and given/known data
ok, i have one loop that has a current source (given as a phasor), a resistor R1, and an inductor L1. in the other loop there is an inductor L2 and resistor R2. something like this:

src resistor dot + (V1) (V2)+
*loop1* inductor M inductor resistor
- - *loop2*
dot

V1 and V2 are across the respective inductors. dot is the dot notation. and M is the mutual inductance.

2. Relevant equations
KVL?

3. The attempt at a solution

my problem is that, with a similar problem expect with a voltage source, i can write kvl equations and solve for the current in each loop then solve for V1 and/or V2. however, i am stuck when it comes down to a current source. should i still do kvl equations?

one more question, for the case of a voltage source, once i solve for current in each loop, is the voltage in (lets say) the second loop = jwL2I2 + jwMI1? where jwMI1 is the induced emf.
