By increasing the magnification the focus is increasing on a particular area due to which the no of light rays which were before more on the entire slide is now decreased due to focusing (magnifying) hence the brightness decreases due to decreased in no of light rays present in that small area
They are not directly related. Brightness is determined by the size and quality of the material doing the magnification (usually glass). Given the same quality of glass, a larger lens will produce a brighter image at the same magnification. This is because the larger surface area collects more light.
the field of very becomes smaller
Increasing the magnification on a light microscope will decreased the diameter of the field of view. You are essentially looking closer and closer at the objects. For example: Using your hand (thumb to fingertips), create a circle as if holding a telescope. Hold your hand-telescope up to one eye and look through it at your screen. Now, move closer to the computer screen... The size of the field you are able to see gets smaller...that's what happens with a microscope lens. As you increase the magnification, the lens gets closer to the specimen.
it will stay the same!!
In a light microscope when magnifiaction increases resolution decreases and the object will apear blurred. It can be removed by putting immersion oil on slides or object which increase the refractive index and cause to increase the numerical aperture which ultimately cause the better resolution as resolution power depends on numerical aperture of lens. The immersion oil used can be cedar oil.
As magnification increases, the depth of focus decreases.
It bends/warps and blurs in a circular shape around the edges, as the light bouncing off of objects is hitting your eyes at a bend relative to your speed.
The field of view becomes smaller when magnification increases.
it becomes bigger
Total magnification is calculated by objective times ocular lens. So if you increase the objective lens is directly related to an increase in magnification.
The magnification of the object will increase.

Adjusting a microscope's magnification settings can alter an object's field of view from a macro to micro areas. Higher magnification make the field of smaller and better defined, where lower settings increases the visible area.

Our view becomes larger and a lot more clearer with a lot of details.
