A pivoted aluminium bar falls much more slowly through a small region containing a magnetic field then a similar bar of an insulating material. Explain.

The direction of the magnetic field lines in a region outside a bar magnet is …..

Draw diagrams to depict the behaviour of magnetic field lines near a bar of aluminium

If a rod of aluminium and other made of insulating material are released to fall in magnetic field, it is found that insulating rod falls faster than aluminium. Why?

How can a small compass needle be used to map the magnetic field due to a bar magnet?

Derive an expression for magnetic field intensity due to a small bar magnet at a point in the end on position.

An iron bar falling vertically through the hollow region of a thick cylindrical shell made of copper experiences a retarding force and attains a terminal velocity. What can you conclude about the iron bar?
