What cases can the Hall Effect occur in with copper wire?

[Phztastic]

What cases can the hall effect happen?
While reading this source. It states : "This is most evident in a thin flat conductor..."

So, can this occur with a copper of wire? In any shape or form?
Or only flat thick whole spaded conductors?

 

[Simon Bridge]

It occurs for any confined current subject to an external magnetic field.
If you are careful with the geometry, you can make the effect very big.

The Hall effect is exploited in some semiconductor devices.
