Think of the rotating disk as a series of concentric rotating rings. Each ring acts as a circular current loop that produces a magnetic field at the center of the disk. Then integrate over all rings to find the total field. What is the expression for the magnetic field at the center of the single circular loop of radius r carrying current I
