Why does the magnet always align in a particular direction?

Why does Be resemble Al?

A bar magnet of magnetic moment 1.5J//T lies .aligned with the direction of a uniform magnetic field of 0.22 T? What is the torque on the magnet if it is aligned opposite to the direction of magnetic field?

mark the statement true or false if the margin of sepals or petals overlap one another but not in particular direction, the aestivation is called imbricate.

Why does BF_3' act as a lewis acid?

A conductor carrying current I direct out of the plane of the paper is lying in a magnetic field directed vertically downwards. Draw the direction of force experienced by the conductor

Why does BF_3 behave as a Lewis acid?

A bar magnet of magnetic moment 1.5J//T lies .aligned with the direction of a uniform magnetic field of 0.22 T.What is the amount of work required by an external torque to turn the magnet so as to align its magnetic moment:normal to the field direction.
