4.1: Magnetism
In Figure 4.1.4 4.1. 4 (a) a magnetic moment m is contained in unit volume. This has a magnetization of m Am. Figure 4.1.4 4.1. 4 (b) shows two such units, with the moments aligned parallel. The vector sum of moments is 2m in this case, but as the both the moment and volume are doubled M remains the same.

SEPARATION TECHNIQUES
SEPARATION TECHNIQUES. If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue)
