Magnification focuses light into a smaller area making it appear more intense.

The size of the cell remains the same no matter what power objective is used. However, the magnification changes between these two objective lenses, with the low power objective magnifying it less than the high power objective.
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
The diameter of a field is decreased by 1.5 millimeters when changed from low power to high power magnification.
It does not. For an explanation of "focal plane" see the question What is the focal plane?
Objectives for higher magnification are usually longer than those for lower magnification ...
Microscope objective lenses are the lenses that you can select on the microscope to change to field of view and magnification.

This is called the nosepiece.

The objective lens in a microscope helps to magnify the object being viewed on the slide. The objective lens can be rotated to change the magnification of the lens and yield a different view.
The rotating structure on a microscope with various objective lenses on it is call the Turret.

when you change from low power to high power the light intensity decreases. this is because the high power objective lens is smaller than the low power lens. therefore, the high power lens lets less light through
the objective is the lens, there is the main ocular lens which you look through and then this leads to the turret. on the turret are 3 (usually) objective lenses which are usually 4x, 10x and 40x. so the objective are three lenses which change the amount of magnification on the microscope. :)
The total power of magnification refers to how many times bigger than actual size you are viewing the specimen with a microscope. It is measure by multiplying the magnification of the eye piece by the magnification of the objective lens you are using. For example, most eye pieces magnify by 10X. So, if you are viewing a specimen with the 4X objective lens, you are actually seeing the specimen 40 times larger than normal. (10X * 4X)
