Consider the flat aluminum disk at the end of a rod swinging into and out of a region of magnetic field directed into the page as shown the in the diagrams below. A) Carefully argue that there are induced eddy currents in the the disk and argue that the eddy currents will be in the direction shown, for each case. B) Carefully determine the direction of the magnetic force on the disk in each case by using the notion that dF=Ide x B. Swinging into field B Swinging out of field
