Homework Statement
A conducting disk (very thin) of thickness h, diameter D, and conductivity [tex]\sigma[/tex] is placed in a uniform alternating magnetic field B = Bosin[tex]\omega[/tex]t parallel to the axis of the disk.
Determine the induced current density as a function of the distance from the axis of the disk. Also mention the direction of the current.
Homework Equations
[tex]\oint[/tex]B.da = [tex]\mu_o[/tex] Ienc
The Attempt at a Solution
From ampere's law, i derirved [tex]\nabla[/tex]xB = [tex]\mu_o[/tex]J. Is my approach correct ? How do i make use of thickness, diameter and conductivity of the disk?
