electromagnetism - How do you determine power flow ...

If you couldn't measure power flow this way it would be very hard for the electric utility to charge you for power. EDIT: The power meter in your house of course touches the wires, but standing on the ground under a transmission line you can do something similar. You can have two pickups, a coil and a straight antenna, and you could feed them ...
