The palm rule is usually for finding the magnetic force on a moving charge and the grip rule is for finding the direction of the magnetic field surrounding a current. They are both ways of specifying the direction of a vector cross product.

That said, there are many variations. See http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magfor.html#c3".

It gets very complicated indeed, because here in the UK we talk about Fleming's Left Hand (Motor) Rule and the Right Hand (Dynamo) Rule; as well as the right hand cork-screw (or grip) rule. All rules use conventional (positive current).
