Question

The magnetic domains of an unmagnetised object are found___________
A.) Parallel to each other
B.) Perpendicular to each other
C.) Pointing towards south
D.) Pointing in different direction

Answer 1

Hint A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction in a magnetic domain. In this question, we have to answer about in which direction these magnetic domains will align in case of unmagnetised material.
An unmagnetised material is that which shows no magnetic properties i.e. it does not attract or repel iron etc.

Complete step by step answer A domain is a region inside of a material where groups of magnetic moments naturally align in the same direction. There can be numerous domains within an object. When there is no external magnetic field present, the domains are oriented randomly so that there is no net magnetic field.
The magnetic domains of an unmagnetised object are found pointing in different directions.(as shown in figure below)

Thus, option D is correct.

Note Magnetic domains of magnetised material are as shown in the figure.

When an external magnetic field is present, the domains will rotate and align with the external magnetic field. When all or most of the domains are aligned in the same direction, the whole object becomes magnetized in that direction and becomes a magnet.
