You can regard disk as very dense wheel of spokes. Each spoke is a conductor and it moves in magnetic field. Hence it will induce current in it.

In continuous disk there are no spokes, but there is something similar: a resistance, hampering electrons to move in tangential direction.

UPDATE

Flux IS changing in spokes interpretation
