This is where electromagnets come in. The magnets are positioned along the path of the colliding beams, and their magnetism is actually used to control their speed and trajectory [source: NOVA Teachers]. Not a bad resume for our friend the electromagnet, huh? From something you can create in...
By themselves, electromagnets are useful things. You can use them to pick up metal objects, carry the objects somewhere and then drop them by just turning off the power. For example, roofers use them to pick up nails that have fallen by accident into a homeowner's yard. And wrecking yards...
This is how electromagnets are made to work. This will be important to keep in mind as we zoom into the structure of atoms. Around the nucleus of the atom, where the protons and neutrons live, there are electrons whizzing around. We used to think that they had certain circular orbits ...

The lenses are replaced by a series of coil-shaped electromagnets through which the electron beam travels. In an ordinary microscope, the glass lenses bend (or refract) the light beams passing through them to produce magnification. In an electron microscope, the coils bend the electron beams the...

so Einthoven developed a better one, which was called a string galvanometer. It consisted of a very thin quartz filament coated in silver, which conducted the electrical current from the heart. The filament passes between two electromagnets, which cause it to move in proportion to the curre...
What are lenses?A lens is a transparent piece of glass or plastic with at least one curved surface. It gets its name from the Latin word for "lentil" (a type of pulse used in cooking), but don't let that confuse you. There's no real reason for this other than that the most ...
