How does NFC work on a physical level?

Question

Physics

Good day.
In general, the whole point is in the title. Tell me, please, where can I read about how NFC and magnetic cards work in principle at the physical level? Wikipedia says that in NFC, communication is maintained by induction of a magnetic field ... Maybe you can do some small experiment to demonstrate this?
Thank you all in advance for your replies.
