What is the magnification of an eyepiece lens in a microscope?

The magnification of an eyepiece lens in a microscope typically ranges from 10x to 25x. This means that the eyepiece lens enlarges the image of the specimen viewed through it by that factor. The total magnification of the microscope is calculated by multiplying the eyepiece magnification by the magnification of the objective lens being used. For example, using a 10x eyepiece with a 40x objective results in a total magnification of 400x.
