Magnetic lens utilize the Lorentz Force which they deflect the charged particles such as electrons or ions. The lens is round shaped with a core of pure iron, surrounded by copper wire (like a simple electromagnet with magnetic force inside). Usually the core of pure iron include four different layers: two outer ones are north poles and the two inner ones are south poles. When charged particles travel through the hole in the middle of the lens the magnetic force will deflect the beam, focus or widen it depending on the type of lens is convex or concave. Another thing important is that there is an electric current running through the wire to create magnetic force so magnetic lens would be heated very quickly as so they need to be cooled down with water or liquid nitrogen.
Magnetic lens have two main aberration types: chromatic aberration (due to the monochrome of the beam) and the spherical aberration (due to the equal spread of magnetic force over the surface area of the magnet's core).
Recently, they use superconductors to create magnetic lens as well to increase perfection of magnetic lens as superconductors can create strong magnetic force in a small region of the core in which improve the correction of spherical aberration. Beside, superconductors can save more power as the current keep running infinitely as there is no resistance. However, as the current is static, it's hard to maintain the strength of the magnetic force that would lead to harsh of maintenance of lens's focal length (the main factor that create the magnification and resolution of the lenses)

How does magnification occur in an electron microscope?
In an electron microscope, magnification occurs through the use of electromagnetic lenses that focus and control the electron beam. These lenses work similarly to optical lenses in light microscopes by bending and focusing the electrons to produce a magnified image of the sample. By controlling the electromagnetic fields within the lens, the electron microscope can achieve much higher magnification than a traditional light microscope.
Which two parts of the microscope magnify the image of an object?
The objective lens and the eyepiece lens work together to magnify the image of an object in a microscope. The objective lens magnifies the image first, and the eyepiece lens further magnifies the image for viewing.
What two parts of the microscope increases magnification?
The objective lens and the ocular lens both work together to increase the magnification in a microscope. The objective lens is responsible for gathering light and forming an initial image, while the ocular lens further magnifies this image for viewing.
How does a two lens microscope work?
A two lens microscope uses a combination of an objective lens and an eyepiece lens to magnify an image. The objective lens captures the image and magnifies it, then the eyepiece lens further magnifies the image to allow for viewing. This combination of lenses allows for high magnification and resolution of the specimen being observed.
Do you add the magnifying power of the two lenses to work a microscope?
No, the magnifying power is not simply the sum of the magnifications of the two lenses. In a compound microscope, the total magnification is the product of the magnification of the objective lens and the eyepiece lens.

How does the microscope work?
A microscope works by magnetizing objects with the glass inside the lens. This lense will show you the small objects you put in containers called slides under the microscope's lens.
What is Ernst Ruska Famous for?
The invention of the electron microscope and work on electron optics
Does a compound microscope have only one lens?
No, a compound microscope uses multiple lenses to magnify the image of a specimen. It typically has an objective lens close to the specimen and an eyepiece lens near the observer's eye. These lenses work together to provide high magnification and resolution.
Which two parts of the microscope magnify the image of an object?
The objective lens and the eyepiece lens work together to magnify the image of an object in a microscope. The objective lens magnifies the image first, and the eyepiece lens further magnifies the image for viewing.
Does a compound microscope have one lens?
A compound microscope has two lenses: the objective lens and the eyepiece lens. The objective lens is used to gather light from the specimen and create a magnified image, which is further magnified by the eyepiece lens for viewing.
How does a simple microscope work?
A microscope is a tube that holds glass lens mounted that have the right focal properties that magnify the image.
What two parts of the microscope increases magnification?
The objective lens and the ocular lens both work together to increase the magnification in a microscope. The objective lens is responsible for gathering light and forming an initial image, while the ocular lens further magnifies this image for viewing.
What are the magnifying parts of a compound microscope and their functions?
The magnifying parts of a compound microscope are the objective lens and the ocular lens. The objective lens is located near the specimen and provides the initial magnification, while the ocular lens further magnifies the image for viewing. Together, these lenses work to increase the overall magnification power of the microscope.
Which two parts of the light microscope magnify the image of an object?
The objective lens and the eyepiece lens work together to magnify the image of an object in a light microscope. The objective lens collects light from the specimen and forms an initial image, which is then further magnified by the eyepiece lens for viewing.
How does a two lens microscope work?
A two lens microscope uses a combination of an objective lens and an eyepiece lens to magnify an image. The objective lens captures the image and magnifies it, then the eyepiece lens further magnifies the image to allow for viewing. This combination of lenses allows for high magnification and resolution of the specimen being observed.
What are the names of some of the parts of a microscope?
There are many parts needed to make a microscope. Some of the parts of a microscope include the eyepiece lens, arm, base, tube, illuminator, objective lenses, diaphragm, and condenser lens.
