This is called the nosepiece.
The rotating structure on a microscope with various objective lenses on it is call the Turret.
microscope has two lenses to increase its magnification
A simple microscope has two lenses. One the eye looks through and the objective lens nearest the object being observed. Changing the objective lens changes the magnification of the microscope, and can also change the amount of light on the object. The objective lens draws the light rays together to make a sharp image.
by the objective lenses
Microscope objective lenses are the lenses that you can select on the microscope to change to field of view and magnification.

The total magnification of a microscope is found by multiplying the ocular and objective together.
It would depend on the microscope, however, there are usually 3 different powered objective lenses on a light microscope, the lowest being of 10x magnification, the middle being of 40/45x magnification, and the highest being of 100x magnification.
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. :)
All microscopes have lenses. Some types of lenses are eyepiece lenses, objective lenses, and condenser lenses.

Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.usually, there are three or four objective lenses on a microscope,
It is to change the objective of the lenses in the microscope
microscope has two lenses to increase its magnification
Used in conjunction with the eyepiece lens, the objective lens is what gives an optical microscope its ability to produce magnified images. There are normally three to four objective lenses on microscopes, ranging from 4X to 100X magnification, where the stronger lenses are larger. When coupled with the eyepiece lens, the magnification of a microscope ranges from 40X-1000X, though special conditions are required to achieve a sharp image at 1000X magnification.
