Why does electricity produce magnetism? How are electrons responsible for magnetism? How is an electric fie...
How do X-rays use electromagnetic waves? How is ionizing radiation used? What subatomic particle was discovered using the cathode ray tube? How does electron capture release gamma rays? How are positrons made? What year was the cathode ray tube experiment?
There are electromagnetic waves around the network cable, and when the electromagnetic waves come into contact with conductors such as metals, a current is generated in them. Since the signal itself is also a current with voltage changes, its essence is the same as the current generated by the...
What are X-rays made of? X-rays are a form of electromagnetic radiation, similar to visible light but with much higher energy. They consist of photons, which are particles without mass or charge, and their energy allows them to penetrate materials and create images of internal structures in ...

A series of electromagnetic coils pull the beam back and forth, scanning it slowly and systematically across the specimen's surface. Instead of traveling through the specimen, the electron beam effectively bounces straight off it. The electrons that are reflected off the specimen (known as ...
There are differenttypes of electricitygenerated throughrenewable and non-renewable sources of energy. History of Electricity In Physics, the law of conservation of energy states thatenergy can neither be created nor be destroyed. This means that in order togenerate electricity, another kind of energy...
Microwaves used for cooking, on the other hand, are electromagnetic waves possessing frequencies around the 2.45 GHz range. Now, electromagnetic waves are waves made up of alternating electric and magnetic fields. For this discussion, we’re more concerned with the alternating electric fields because...
Magnetic lines of force, or flux, are measured in Webers (Wb). In electromagnetic systems, the flux relates to the current. A field's strength, or the density of the flux, is measured in tesla (T) or gauss (G). One tesla is equal to 10,000 gauss. You can also measure the field...
How are electromagnetic waves generated? How are microwaves and infrared waves similar? What do they both have? How are electromagnetic waves propagated? Is infrared light made of mechanical waves? What are the different types of infrared waves?
