Flux Linking with Aluminium Disk Above a Vertical Current Carrying Rod: AC vs DC

[jsmith613]

Homework Statement

If an aluminium disk is placed above a COMPLETELY vertical current carrying iron rod will any flux link with the aluminium disk ASSUMING ideal situations

Homework Equations

The Attempt at a Solution

------

I think not because the current carrying rod produces a circular field around itself (right hand corkscrew rule) but am not sure...can someone please confirm this :)

also, why is it important if the current is AC or DC?
