What is one bar?

What is a neutral point in a magnetic field of a bar magnet.

Two similar bars made from two different materials P and Q are placed one by one in a non-uniform magnetic field. It is observed that bar P tends to move from the weak to the strong field region and d. What is the nature of the magnetic materials for making these two bars? Show with the help of a diagram, the behaviour of the field lines due to an external magneic field near each of these two bars.

A bar magnet placed in a uniform magnetic field of strength 0.3T with its axis at 30^@ to the field experiences a torque of 0.06Nm. What is the magnetic moment of the bar magnet?
