Griffith echoes Terman.

Terman writes on page 2 of his 1955 edition:
"The strength of a radio wave is measured in terms of the voltage stress
produced by the electric field of the wave and it is usually expressed
in microvolts per meter."

Terman does not literally mean that it is the electric field which is
measured. In his handbook Terman says that a magnetic loop antenna is
usually the field strenngth meter`s antenna. Terman meant that field
strength is quoted in volts per meter. It is irrelevant which field is
actually measured as the two fields are locked in magnitude by the
impedance of space, 377 ohms. If you know one, you know the other.

Terman also wrote on page 2:
"The strength of the wave measured in terms of microvolts per meter of
stress in space is also exactly the same voltage that the magnetic flux
of the wave induces in a conductor 1 m long when sweeping across this
conductor with the velocity of light."

The electric and magnetic fields serve to recreate each other in their
flight from their source. Either could be measured to get the strength
of the wave. Neither field directly produces volts in a wire.

As Terman says, it is the wave sweeping the wire at the velocity of
light, the d(phi)/dt that generates the volts.
