The current in A varies linearly. The current in B is constant. 
So, the magnetic field of A+B varies linearly.
A and B are both in this magnetic field which varies linearly.
According to Faraday’s law, the induced voltages in A and B are 
proportional to dB/dt which is constant.
The induced voltage and current in A with or without the presence of B is 
the same.
So, the energy dissipation is zero with or without the presence of B.
