No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
The magnification. What really matters about a telescope, the single most important piece of information, is the diameter of the main lens, or main mirror.The magnification.

What really matters about a telescope, the single most important piece of information, is the diameter of the main lens, or main mirror.
a telescope's magnification is calculated as the ratio of the focal length of the primary objective to the focal length of the eyepiece. Since a telescope is defined by the primary objective, this part of it is essentially unchangeable. Therefore, the way to increase magnification is to decrease the focal length of the eyepiece. For example, a 1000mm objective and a 25mm eyepiece yields a magnification of (1000/25) 40x. Changing the eyepiece to a 10mm eyepiece increases magnification to (1000/10) 100x.
The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.
The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece. In this case, the magnification would be 3000 mm (telescope focal length) divided by 15 mm (eyepiece focal length), which equals a magnification of 200x.
The apparent magnification of telescope optics is(focal length of the objective) / (focal length of the eyepiece)= (1,000 / 25) = 40 .The diameter of the primary mirror has no effect on the apparent magnification.The length of the body tube is involved in the case of the Newtonian configuration,only because it has to be long enough to hold the eyepiece in the right place.

The magnification indicates how much bigger something will be seen. For example, with the naked eye, the Moon has an angular diameter of half a degree; with a 40x magnification, it will look like it has 20 degrees.
The light-gathering power of a telescope is determined by its aperture, which refers to the width of a telescopes primary mirror or objective lens.
The formula for calculating the angular magnification of a telescope is: Magnification focal length of the objective lens / focal length of the eyepiece.

Magnification is inversely proportional to the diameter of the field of view.

Good for what? Telescope? Microscope? "Magnification" is often used as a marketing tool; telescopes for example might come with a maximum magnification that is too big to get a clear image, just so they can claim "100x magnification" or whatever. And it is cheap to get a magnification that is clearly too much. The most important piece of information about a telescope is, how big is the main lens, or the main mirror. A larger diameter here will give you (a) more light-gathering power, allowing you to see fainter stars, and (b) more resolution, roughly equivalent to usefulmagnification.Good for what? Telescope?

Magnification refers to a telescope's ability to make an object appear larger when viewed through the telescope. It is the degree to which the image of the object is enlarged compared to what is seen with the naked eye.
