I am learning about loop antennas at the moment. I read that the response of a small loop Antenna is proportional to the rate of change of magnetic flux through the loop which causes a uniform current distribution in the loop. This would be Faraday's law. However, then we got a large loop (wavelength is as big as the circumference); how do we describe the interaction? Let's say, there is an incident electromagnetic wave going through a large loop. Can we still use Faraday's law to describe the response and is it the same response as in the case of a small loop?
This might a stupid question. I read in some books that small loops can be described using Faraday's law but they don't use Faraday's law to describe big loops.
