  Hi everyone, I'm working with the concentric coil of the image (Simulation on Ansys Maxwell). I would like to know how I can measure the induced voltage on the Receiver Coil (Yellow). In this case I'm using eddy current solver. For Transmitter Coil (Orange) I'm assign a winding coil for current excitation (Type of current is solid). For the Receiver Coil I'm assign a winding coil for voltage excitation (In this case I'm only use resistance and voltage parameters, 1kOhm and 0 V). Finally, for analysis Set up, I'm assign an adaptive frequency of 5kHz.
  
  Many Thanks.

  Hi,
  
  Can you share more information on how you have defined the terminals of the receiver coil?

  Hi,
  
  Basically I'm apply the same principle of Transmitter Coil. I'm add a Winding --> Voltage (Solid), and I'm assign 1kOhm for resistance parameter, and 0V to Voltage parameter. Then I'm select each face of the Transmitter Coil Terminal and Assign Excitation --> Coil Terminal. Finally I'm Add each Terminal Excitation to the Winding. For both Coil's, the terminals at the bottom are the Input parameter (For current and voltage), and terminals at the top are the Output parameter (For current and voltage). Also, each terminal are in contact with the face of the region. I'm not sure if this is the correct configuration for Receiver Coil to measure the voltage, because in the practice, When a current is apply to terminals of transmitter coil, the induced voltage is measured on the receiver coils.
  
  Many thanks.

  Hi, @AndresC,nIf you want to get induced voltage in the receiver coil, I'd recommend you to make the assigned excitation for receiver coil as close to reality as possible. For example, you can assign a current excitation I=0 A if you use a voltmeter in real case since it's an open circuit. If you know the resistance of your voltmeter (R=1 kOhm for your measurement set up?), assigning an R and V=0 would also work.n

  Hello All..
  I am also stuck on the same issue, I want to calculate the induced voltage. I am new to Maxwell. How can eddy solver solve my problem?
  Two coils, tx and rx ... the tx coil is excited with 200A current, and want to see, how much voltage is induced on the rx coil.
  will be thanksful if can someone help me.
