In a ferrimagnetic substance, on applying a magnetic field, the magnetic moment of the domains are aligned along the direction of the applied field.

Here's a step-by-step explanation:

1. A ferrimagnetic material is a type of magnetic material that has two populations of magnetic moments, one larger than the other.

2. When no magnetic field is applied, the moments of these two populations are anti-parallel, but not equal in magnitude. This results in a net magnetic moment for the material.

3. When a magnetic field is applied, the magnetic moments of both populations tend to align with the field.

4. However, because one population has a larger moment, it dominates the alignment. This results in the overall magnetic moment of the material aligning along the direction of the applied field.

5. The alignment of the magnetic moments with the applied field is what gives ferrimagnetic materials their magnetic properties.
