Dear Seonho Yang,

the “Hysteretic Core” block has “Loss Energy” as an output that you can probe.  
I have attached a small model probing this core to get the core loss and BH curve using an XY plot.

If you need further assistance, please write to [support@plexim.com](mailto:support@plexim.com).

Best regards,  
Reto
