[zapped]

Homework Statement

a bar of magnet is hung from a string through its center. A charged
rod is slowly brought up into the positions shown(down)
in what direstion will the magnet tend to rotate?
Suppose the charged rod were replaced by a bar magnet with the north pole on top.

N magnet S

Homework Equations

in what direstion will the magnet tend to rotate? Is there a difference between what happens to the hanging magnet in the 2 situations? Explain why you either do or do not think so

The Attempt at a Solution

The positive charge of the rod will repell the magnet and it will rotate clockwise
if the rod were to be replace it will be the same
is it right?
